A glad, cr90, neb, and mc30 are the same on the motti scale. I propose taking the average of command value and motti value to arrive at a slightly more granular ship strength measure.
4 AFii's clocks in at 4 x (2+3)/2 = 10
3 ISD's is 3 x (3+3)/2 = 9
5 VSD's is 5 x (2+3)/2 = 12.5
9 cr90's is 9 x (1+1)/2 = 9
7 neb-b's is 7 x (1+2)/2 = 10.5
mc80 (3) + 3 x mc30 (4.5) = 7.5
