What is the percentage penalty for the penalized SA's?

Only Bort know this...

I've read cryptic answers from people that wouldn't have a clue that hinted at basically -1 for those SAs.

This is coming from someone that doesn't really know that listened to people that pretended to know. lol

Catch brought up a theoretical 20% at one time and then said that it isn't 20%. It's also been suggested that the penalty is not constant and may be a different percentage for some SAs than others. I'm not sure that I buy that, though.

It doesn't seem like a deal breaking percentage, good SAs are still good even when penalized and when favored they aren't op'd. Power Thru is still good on an elusive back, Sticky Hands is still good on a speed WR.
