Sometimes people forget about when a Pokemon is slower or faster due to less speed EV's or Choice Scarf. This could easily be fixed with the team preview under the avatars. If a Pokemon is slower then your Pokemon, but would outspeed if it was max speed, then instead of [Minimum base speed] to [Maximum base speed] then it would say [Minimum base speed] to [Base speed of your Pokemon that was faster due to the other Pokemon not being max speed]. For Choice Scarf if a Pokemon outsped another Pokemon that it could never outspeed, even with max speed and the speed boosts it has, then it would reveal that Pokemon's item to be Choice Scarf.
