I indeed missed Gymnastics in my list. When going through the different sports I simply overlooked it. I do think one or two medals are possible.
I added Golf because I generally think that everything is possible in Golf.
And IMO it's highly doubtful that Zverev will even play at the Olympics, much less win a medal.
In general, I added the number of medals that are IMO realistically possible. Sure, it could be more in some events, but that seems highly unlikely to me. German Shooters were way too bad so far in qualification to add more medal chances.
