I've been tinkering with a few minor modifications to some of the ships in KA/RA.  For instance, I was looking at creating Fast Cruisers that were actually fast by using Tech +1 engines, conversely slowing down the Romulan Eagle ships with tech -1 engines, or creating disruptor armed battle stations for the Klingons.

I've punched the ships systems into the various spreadsheets and even worked some out manually, but in only a few cases to the numbers come out right.  The space differences I have no problem with (many of the ships have way more systems on board than allowable in 'standard' Starmada hull size limits) since as far as I can tell, only the hull points actually on the ship matter for the CRAT calculations.  However, even looking just at the CRAT, I can only occasionally get a ship to match up exactly with the printed values.  The differences are usually small (10-20 points), but can get fairly substantial for something big (like the battle station).

Am I just missing something in my calculations or is there a certain amount of fudge factor (proprietary math?) at play.  I will happily fudge the numbers myself if that's the case, but if I'm missing something I'd like to find it, especially as it would allow me to post some of those ships onto the forum for others to use with reasonable confidence in the values.

Thanks
