@SoloAD: Thanks! =)
Anyway, if I understand this right:
(17,777,7600=8888.8*2000, all percents are converted to decimals, all decimals are rounded
to 2 places, and "n" is the total number of engineers on board)
As I don't have access to many good engineers, I can't really test it. However from pics
that I have seen (eg: http://www.navyfield.com/board/view.asp?Num=127672&Sort=C06), it
works for 1 sailor.
(Interesting that 1/sqrt(n) is so close to what Adalbert found for stacking)
