To clarify - if one Pokémon is used in battle from a team of 6, the EXP all would give 50% to the Pokémon used and 10% to the others, a total of 100%. Whereas the EXP share gives 100% to the Pokémon used and 50% to every other Pokémon, a total of 350%. So turning the EXP share on in these circumstances results in levelling up 3.5x faster?
