I really didn't have much to add to the discussion, but thought I'd share. I have the R and the 3 to 5 FPS mechanical (don't remember what it is supposed to be) I get when tracking isn't ideal for sports, so I tried the electronic silent shutter. I shoot a lot of soccer and don't really like shooting with my 80D anymore (need to upgrade to the R6). If the action isn't that fast, then it works okay. Usually it is just the ball that looks funny, but then you get photos like this... I know it is terrible composition and clearly a throwaway. I had a ref just to the right of me.
