The case of 500 peasants vs. 1 dragon is interesting. In this case
both sides have a total AF of 500, and the peasants have a huge
numerical advantage, but (since the peasants can only come at him 4 at
a time) the dragon still has a small but real chance to win the
battle.
For comparison, how do the two systems compare in the "1 dragon vs. N
knights" battle?
% battles won by the knights (1000 trials)
# Knights Current System 4:1 Rule
---------- -------------- --------
3 34% 26%
5 64% 45%
7 79% 61%
9 90% 72%
11 96% 82%
Note that even for 3 knights, the winning percentage is down, because
the 4:1 rule limits the number of blows in a row for a side, not
really the ratio of attackers to defenders.
