I play on a course that has a fairly significant difference in slope and rating for the front and back 9. Front 35.4/131 back 36.8/139. When I play 2 consecutive rounds on either the front or back the slope gets calculated correctly, i.e. Two consecutive nine hole rounds on the back gives me a slope of 139, but I always get the same rating 72.2 regardless of which side I play. I think it should be that the rating would be 73.6 for two consecutive rounds on the back 9 and 70.8 for two front 9 rounds.

No response? Is this the official location to submit bugs with the site? Clearly the rating calculation is wrong when combining 2 9 hole rounds.

Send mustang6560 a private message or email and you will probably get a quicker response.

ryttingm,

I apologize for the delayed response. I'm not sure how I missed your original post.

There is a bug related to 9-hole courses. The rating is divided in half, which makes it a 1/4 of a full rating. We are aware of the issue and it's on my list of bugs to fix.
