I was thinking -25, +3,+4,+5, +1. At 30 Ranks the skill bonus is 120, 40 points higher than the normal 80.
The bonus for EV skills at 30 ranks is 95 (in RM2 progression). Occ is 110. Normal is 80.
For completeness, the ascending progression as EV is 150. Occ is 180. At two ranks per level, EV is 210. Occ is 270. That's 60 ranks purchased at level 30 (120 ranks for EV and 180 ranks for Occ).
