Game Mechanics: Dwarf Cleric exp gain

[Gorgetrapper]

It would seem that the math is wrong, because normal experience should be considered 1.0, penalties are beneath that...

So as a troll sk, it should be .6 x .8 = .48, which to me, means a 52% penalty, and not 68%.

What are the experience penalties/bonuses?
By Race:
Troll -20%
Iksar -20%
Ogre -15%
Barbarian -5%
Halfling +5%

By Class:
Paladin / Shadowknight / Ranger / Bard -40%
Monk -20%
Wizard / Magician / Enchanter / Necromancer -10%
Rogue +9%
Warrior +10%

Exp penalties are multiplied not added, so a troll sk would be (1.4 x 1.2 = 1.68 or 68% penalty).

Halfling warrior would be 1.05 x 1.1 = 1.155, or a 15.5% bonus.
Halfling rogue would be 1.05 x 1.09 = 1.1445 or a 14.4 (or 14.5)% bonus.
Troll Warrior would be .8 x 1.1 = .88 or a 12% penalty.
Ogre Warrior would be .85 x 1.1 = .935 or a 6.5% penalty.
Barbarian Warrior would be .95 x 1.1 = 1.045 or a 4.5% bonus.
Troll Shadowknight would be .8 x .6 = .48 or a 52% penalty
Ogre Shadowknight would be .85 x .6 = .51 or a 49% penalty.

I think you get the idea. If this is wrong, please correct me because as far as I am concerned, bonuses go ABOVE 1.0, and penalties go BELOW 1.0 and you're supposed to multiply the numbers together and the difference between the two numbers compared to the neutral 1.0 should be the penalty or bonus percentage.
