26 would work for me too, but the only 6 that were winnable that he lost were:
2019 Wimbledon
2009 USO
2009 AO
2008 Wimbledon
2014 Wimbledon
2015 Wimbledon
Some will think 2011 FO was winnable, but I don't think Fed was ever beating Rafa on Chatrier.
Good list. I’d rank them :
2019 Wimbledon
2009 USO. ( Was in complete control)
2008 Wimbledon. ( Could have went either way)
2014 Wimbledon ( Had chances to break in 5th)
2009 AO. (Ran out of gas in the 5th)
2015 Wimbledon.
throw in these SF
2011 USO. Double Match pt
2010 USO Double Match pt
2005 AO (Serving Match pt v Safin in 4th
Would have steamrolled Hewitt in Final)
Easily could be on 23-24.
