Speed Infusion 11 does not work

I know, that's what I'm saying. Our max speed is Faster (2). Other versions have a max speed of Faster (1). With Buccaneers, with booster alone out max Speed is (3). With SI 1 it becomes Faster (2). With SI 11 it's supposed to be Faster (1), but I'm saying it remains Faster (2). In other versions of the game, it would be reduced to Faster (1), thus being useful to both Buccaneers and Night Lords. However, since our Faster is still capped at (2), 11 SI remains only useful to warriors who generally don't have a chance at breaking Faster (2) either way.
