I have noticed a typo in the Crobat analysis. I found this in the optional changes.
"Crobat has a wide variety of EV spreads it can run, due to the different roles it can fulfill. You can reduce the Speed number to 144 EVs, as this puts Crobat at 356 Speed, just enough to outpace +1 Speed Tyranitar.
Those speed EV's put Crobat at 365 speed, not 356. If you only had 356 Spe, you wouldn't outrun base 115s nor Scarftar.
