New Equipment Stats
By Kickntrue on 6/15/09
You guys know we've been tracking equipment data for some time. You should probably never buy a club again, without seeing this new oobgolf feature.

We now have equipment stats for Drivers, Wedges, Irons and Putters sortable by handicap groupings. They show key stats for an individual club based on relevance (so for Drivers you see Fairway %, for Irons GIR, etc). You can also see key stat improvement. What that means is- what happened when someone switched from another club, to THAT club, so it's telling of the equipment, not just how good the players are. Also included in the rankings are how many users use a piece of equipment and what it's user rating is on oobgolf. All of this combined in a magical formula gives you rankings of the best equipment you can buy.

Finally, you can cut through all of the marketing hype from these golf companies and actually see what the best performing equipment is for your game!

So that one or two players can't make a random piece of equipment shoot up the leaderboard, a minimum number of of users is required to hit the leaderboard. If you haven't been tracking your equipment before, this should be a great reason to start doing so!

This page will be continually updated so it's always using the most up to date stats from our 400,000+ recorded rounds from you guys!

As always- feedback is very welcome!

This is a great feature, however it might not say much about equipment performance. While these stats can certainly show a correlation between a particular club and performance, they most certainly can't prove causality. What I mean just because a particular driver shows that it hits more fairways in your database it does not mean that the higher fairway percentage is because of the driver. There are just too many other variables, namely the people playing those drivers.
For example, beginners would very seldom buy $1k Callaway iron sets or $500 Nike drivers. They would probably buy a cheap $200 complete Wilson set. So scores from the beginners with the Wilson sets would be much higher than from the Callaway sets or the Nike drivers that are usually bought by people who are already committed to golf and want to improve their game by buying a "better" club. These scores would naturally be lower.

Continuation of last comment:
Now, is the better score because of the Callaway or Nike club or is it because the person who buys the Callaway or Nikon clubs is already better?
While these stats are interesting to watch, they are most definitely not the way to pick a club.

gtakacs, thats why it is divided it by handicap. agreed that viewing across all users it doesn't mean nearly as much as if you look at a specific handicap group.

Addition to my earlier comment:

I have looked at the data and while you guys certainly tried your best to eliminate the player variance, I don't think you have. You group people into different handicap groups,but these groups have a variance of 5 strokes. On the <6.9 handicap group the difference of fairway% between the best (66%) and worst (42%) driver is 24% which is more than 50% improvement over the 42%. The question is how this improvement converts into reduced number of strokes? If the improvement is less than your gap of over 5 strokes just due to player variance then it's most definitely hard to say the improvement was due to a better club.

gtakacs says:
Another interesting fact to ponder that the best driver in the lowest handicap group hits fairways 66.7% of the time while the best club in the highest handicap group hits fairways 60% of the times. So which driver is better? That is less of a difference than the variance between best and worst driver in the best handicap group. The question is how can someone hit 60% of their fairways and still end up with 28+ over par most of the time while another guy can do the same and be a scratch golfer. I'll tell you how. It's the short game.....

klangdon says:
gtakacs, your looking at it from a single golfers perspective. If I looked at just your stats there is no way I could say that a fairway % improvement was based on a specific club. However if I look at 20 golfers and 200 scores and the fairway % improvement is +6% with one club and -4% on another club, I think its pretty reasonable to draw the conclusion that one club is going to hit more fairways than the other.

Ben Crane says:
True, but you also must consider that not everyone was playing the same model of club before switching. Some of your clubs are only played by 8 people making the variance greater as each player has a greater impact on the number.

klangdon says:
Thats why the overall rank is partially based on the number of users using it. This give more weight to clubs that have better data (used on more scores). Because of this there isn't a club within the top 20 that has less than 30 users and about 250 scores against it.

Look, I am not argueing that this data should be published in some journal. I am just saying that we presented it in the best possible manor to help people in purchasing decisions. If you have better ideas, we would love to hear them.

I like it. When I go searching for my next new club, I will check this out. It's not a replacement for going out and hitting a few, but it gives you an idea of what other golfers of a similar skill level are using, and how much it helped. It's not perfect, but rankings based on these types of stats rarely are.

gtakacs says:
@klangdon, I agree that you certainly have tried your best with the data available to you and we certainly appreciate it. It is better than nothing. But only if people looking at the data understand that there is some severe limitation as to what one could/should conclude from it. I, personally, most certainly will not pick my next driver based on the results that might indicate correlation, or even causality but still can be statistically insignificant and could suffer from small sample bias.
For more information on the subject I recommend these books:
Freakonomincs
Golfonomics
The Mad Science Of Golf

@everyone... All I know is, at 3k scores posted a day, the data is going to be very good, very quickly. For the record- I'd also recommend Freakonomics. I actually used portions of the book to talk my wife through her C-Section last week.

as far as I can tell, here's another issue with the stats

I have a driver, fairway wood, hybrid and long irons that I often tee off with, and although I do input the club I use off the tee, the equipment stats that this site keeps do not seem to differentiate which club I used off the tee

for example,

looking at my fairway stats for my driver, I see the same exact percentages as when I look at fairway stats for my fairway wood or hybrid

my fairway percentage can show a big improvement for the driver, but really maybe the improvement is due to more accuracy from the 3wd or hybrid

for example, maybe I hit 3wd 5 times a round and driver 5 times, if I hit the fairway 100% with the 3wd, and 0% with the driver.. my stats will read 50% fairway for both clubs

maybe some people rely 100% on the driver to hit all tee shots on par 4's and 5's but for many golfers, the fairway stat does not

If I'm mistaken please correct me, I would imagine it should be an easy stat to fix for the guru's on this site

What about a golf ball stat? (sorry if it has already been asked)

I hate to say it, and I'll probably get some flack for doing so, but this was a total waste of time. This whole thing just wreaks of "Hackville". Every club on the market today produced by any of the leading companies is a quality product. To use another persons stats to help choose golf equipment is insane!!! Just go to you local Golfsmith and take a look at the "used" rack to see every driver, iron set, putter and wedge listed on the top of these new stats. It shouldn't matter one bit what another man uses in his golf bag when choosing YOUR clubs. The only way is to try them, have them fitted for your swing and wait for them to arrive. Some people are off the rack kind of guys that need re-assurance from others to make a purchase, that just doesn't serve you well in golf. I play with some decent golfers, and none of us have more than one club in common.

I feel the need to repeat a post I posted a while ago, I love this site, I think it's one of if not the BEST social networking golf site on the internet. That being said, I think you guys would be much better served enhancing the social features to the site. THE STATS ARE FINE!!! Can I get an email when someone post on a subject that I posted to?? How about an email when someone post a score at a course that I'm "watching"?? I understand you guys are numbers guys, but come on, spend some time on the social side PLEEEAAASSEE!!!

klangdon says:
@Ward, yes some parts of the site do not take into account which club you have selected off the tee (launched prior to that capability and waiting to be upgraded). These stats however are based on you choosing "driver" off the tee.

When Ford wins a Nascar race on Sunday, they sell more cars on Monday. When someone wins a major with a Burner or an R-7, everyone has to have one. A long time ago, a friend of mine who beats me by 6 or 7 strokes, swapped bags with me for one round. Guess what he beat me by 7 strokes. I have to agree with Ben Crane, the player, has the most influence on the outcome.

Gentlemen; The Stats are fine, but does everyone need "Game Improvement Clubs"? I derive greater pleasure in this game when I play one of my five sets of what might be considered "Vintage or Obsolete" items and post resonably low scores. Some of these clubs were produced prior to 1975 and produce the desired results if "I Do My Job Properly". It is "Great Fun" to hit a drive with a persimmon driver out to 250'-260' within 10yd. of my point of aim and watch my playing partner use his "Giant Tin Can" (twice the size)to try to hit 270-280+ and end up OB! Older clubs require skill development and practice but are much more fun. Try playing a set of Wilson Pro Staff FG-17's sometime and tell me what you think. I recorded a number of decent scores over the years with those and they aren't for sale at any price. Also TR has a good idea in his post. JWHpurist

thanks for the update klangdon, maybe sometime in the future it'd be really slick to be able to compare fairway stats for driver vs 3wd or whatnot

great stuff though as usual, I love this site

Any chance you could add driver distance to this?
6/17/09
 
klangdon says:
fraserjr, we are looking to add driver distance. we have to scrub that data first as ALOT of users are putting 0 into driver distance columns when not tracking it...

I'll second ToddRobb's comments, although I do appreciate the stats (wish mine were better). Anyhow, it'd be great to be able to link up with other solo golfers for rounds locally, maybe in some sort of weekly messageboard attached to each course or by zip radius.
