The average at Wimbledon has been c36 wins - last season we got 39.
At the AO this season we got spot on the longer term average; the FO looks like landing pretty close to the average over the years
So, I am going to set 36 as the midpoint for Wimbledon this season - just a tadge lower than last year - and the range will be 27 or less to 46 or more.
