Ah, misunderstanding. I'm thinking 61 in one race!
On the way down, SR = C is the worst and can knock you right down to 0.
But you are right, it is also amazing, how much bumping is going on in SR=A. (Because the system does not work long term)
One more thing: I know, I am not allowed to say this here, but regardless of SR, if you have 2 or more French kids aka Fronks directly behind you, you are in for trouble. I saved my SR=99 this time by letting 3 of them pass, i.e. get away with their squeeze, but this is not a thing I'm going to take up as a hobby...
It is often best to always defend the inside - even in cases where no sane person would go for an overtake there...
