By the way, if that program is not wrong and I've not miscalculated it could be possible to balance the values by increasing the maximal attack of Fri0s and decreasing their minimal attack.
I don't understand this, cause the meridian of attach will stay the same if increased and decreases by the same value. Perhaps you could provide your values for test.
Because the values are close to each other, the probability is high that soldiers need one more hit even though the opponent is almost dead. If the difference between the values increases this probability gets lower.
I don't have some values, but I experimented a bit and it seemed to work.
