When appraising a Pokémon, the team leader tells you which IV is the strongest. Then they give you a hint, as to what the value of the strongest IV is.
For example, if you're on team Valor, the leader might say "Its HP is its strongest feature.", followed by "its stats indicate that in battle, it'll get the job done.". Which means that stamina is the highest IV, and it has a value of somewhere between 8 and 12.
Given that, can you assume that the other IV values are not within that same range, or just that they are lower than HP?
If stamina was 11. Could attack be 10, or does it have to be 7 or less?
