Stacking penalty mod for Nth module or rig =
0.5 ^ [ ((N-1) / 2.22292081)^2 ]
1 : 1.0000000000
2 : 0.8691199806
3 : 0.5705831430
4 : 0.2829551534
5 : 0.1059926494
note: modules with highest bonuses are calculated first.

Align time (seconds) =
[mass(kg) / 1mil] x inertia x 1.386

Lock time (seconds) =
[40000/ScanRes] / [asinh(SigRadius) ^2]

Skill training rate =
Primary attrib. + [0.5x Secondary attrib.] SP per minute
