I know Chris was going to do a bit on this but ill post my findings as well
Each research line has 10 levels.
The amount of Research points gained per kill is capped at (roughly) 5% of a research level.
So far I've got the following (in XP, 1SK = 1000XP)
Code: Select all
Level Cap per kill Total required for a level to be "trained"
Level 1 2,500 50,000
Level 2 22,500 400,000
Level 3 80,000 1,600,000
Level 4 235,000 4,700,000
Level 5 637,500 12,750,000
