bug: Super soldier calculator doesn't work

Everything is fine.
Sometimes Natural enemy and Friend bonuses doesn't affect the results:
Strength needed: 2750
Current strength: 2707
Case 1: Training with 200%, 1 friend and NA: 17 points
Case 2: Training with 200%, 0 friend and no NA: 16 points

Case 1: 2750 - 2707 = 43 / 17 = 2.53 days
Case 2: 2750 - 2707 = 43 / 16 = 2.68 days

Concluson: In both cases I would need 3 days to get SS
