You want to know where you went wrong?
The Serve statistics overview does not include unforced errors off the return
Unret = Unreturnables
FcdE = Serves where the attempted return was a forced error
That unret is actually service winners. Fed had 8 as per that
FcdE is for forced errors on the return - 26
Roddick had 5 UEs off the return:
1st set at 2-3, 30-15
2nd set at 3-4, 0-15
5th set at 1-1, 15-15
5th set at 1-1, 40-15
5th set at 6-6, 40-30
which brings # of Federer serves unreturned to *drumroll* 89. (50 aces+8 service winners+26 errors forced on the return+5 unforced errors on return)
The fact that you chose to make FcdE as roddick error on serves (did not bother to mention forced when it says forced errors clearly) goes to show you are either:
a) clueless
OR
b) mendacious bullshitter
I already pointed out the correct place to look for with a screenshot - the return statistics for Roddick. But you didn't think twice about what I pointed out, did you?
