I understand how your handicap is calculated.  This post is focused on the rounds used to make that calculation.  Under the title "How is the USGA Handicap Calculated" on this site under the heading "How many Rounds Used", it states the following "20 Rounds in the last year, use the best 10 rounds".

Today is 7/23/10 - is it calculating on the calendar year, i.e. the best 10 rounds since 1/1/10 or is it the best 10 rounds for the last 365 days? I would think it would be the latter since an active golfer will always have 10 rounds posted and they aren't going to start over every January 1.

On the score summary page, the best 10 rounds that are used to calculate your handicap are highlighted so you can see which ones are being used.  The "oldest" round being used for my calculation is February 15, 2010 (only 5 months ago).  The highest two scores in my 10 rounds are an 87 on 5/25/10 and an 85 on 4/29/10.

Here's my question - I have 3 scores within 365 days of today that are lower than the 85 and 87 - why aren't two of those scores being used?  By the way, all three are in 2009 which tells me they may be using the calendar year which doesn't make sense to me.

Any explanation from the administrators would be helpful....Thanks!!!
