Rounding Errors in Ship Capacity?

from GalCiv3 Forums

Either a rounding error or a small bug, but when you research hull capacity focus you should get a 20% increase to hull capacity.  However it looks like we are only getting a 16.6% increase across all the hulls.  So for example Medium hulls go from 90 to 105 capacity instead of 90 to 108 if it was a full 20%.  Does anybody know a good way to get into the micro, and get the decimals instead of just whole numbers to verify this further?

Your math is off. You assume that the bonus is a compound bonus. In reality it is a flat bonus against the base capacity.

Your medium ship has a base capacity of 75. Lets assume you research a 20% capacity increase:
Compound: 75 * (1.2) = 90
Flat: 75 * (1 + 0.2) = 75 * 1.2 = 90
No difference here. 

Then you research a second 20% capacity increase:
Compound: 75 * 1.2 * 1.2 = 108
Flat: 75 * (1 + 0.2 + 0.2) = 75 * 1.4 = 105
But here is your difference. 

Hope this clarifies the issue.

Cool, didn't know it was cumulative percentage gains off the original hull size.  Thanks for clearing that up!
