So I've got two ranks of Perfect Self, and everything seems to be in order (+2 extra bonus all over, and +4 to all the stats) except having just made 14th level, I see this one oddity:

Forest Gnome, Level 14

Strength	74 +2	78 +4
Constitution	66 +18	70 +20
Dexterity	74 +17	78 +19
Agility	47 +9	51 +10
Discipline	66 +13	70 +15
Aura	84 +17	88 +19
Logic	77 +18	81 +20
Intuition	77 +13	81 +15
Wisdom	84 +22	88 +24
Influence	62 +1	66 +3

For the life of me, I cannot figure out how the stat can go up by four but the bonus only by one. All of the other odd stats (looks like only two, Logic & Intuition) calculate out at +4/+2.

I had glossed right over the fact that I was passing the +0 mid-point; good catch.
