Of the two, I would think the Serena type FH would be more error prone than Fed's as far as timing is concerned since it incorporates more variables. Bottom line is, there are many ways to hit the ball...
I think you are very right, and also want to point out that Serena does many
different things and does tend to be a bit streaky with her play. Sometimes
crushing the better players, then other times struggling with avg players. She
does struggle with timing in quite a few matches. Fed is way more consistent imo.
