Thanks Alonso.
I too have experienced this issue on numerous play through's. The 'chance to learn' percentage rates are not being calculated properly for certain types of arcane spell casters. In several tests I have seen between double and triple the expected number of failures. This is with non-specialist mages learning spells at or below their spell caster level.

After some poking around, I've found that this is an original BG2 bug. Reported internally.

Looks like there is a similiar problem with wild mages. I attach a saved game prepared to test it with Neera. There's more information about this in the first thread I mentioned.
