Sometimes I just can't figure out how the unit strength value is calculated in combat. For instance, yesterday I was sinking poor outdated barbarian ships with my sub, and when peeking at the combat preview I saw this:

Why is the caravel's strength listed as 6 and not 15? And why is the sub's strength listed as 130.8 and not 60 * (1 + 0.6 + 0.33) = 115.8? Does anyone know the formula the game actually uses?

60 * 1.33 * 1.60is a bit closer,128, but still not quite there. Maybe it's base damage is really61.3and it's rounding heavily to60:P – Nick T Sep 10 '11 at 10:32
