i believe
flamestryke's site has a complete table of xp. the 20%/40%/60% increases are as scatter described, but xp requirements only double up to level 11, after which they fall to about 60% of the previous level.
i dont dual often, but i'd like to try mage to sam dual in a small party - if i ever figure out how to make a sam i like!!
one dual i found i quite liked was mage (one level) to bishop. the higher starting intelligence, coupled with the high bonus points means getting powercast 1 or 2 levels faster than straight bishop, at the sacrifice of getting non-mage spells one level later. of course, it only works for faerie, elf, and (IIRC) gnome.
edit: powercast not powerstrike
