I think C&G does give an overall correct feel to the game even when things do not go your way when you expect them to.
I would agree with that. I would definitely like to try them again a few more times and see what happens.
I can think of a number of other rulesets where "lucky" or "unlucky" die rolls have lead to events that should in theory never happen given the situation and conditions.
Absolutely, remote but possible outcomes should be accounted for. However, what we ended up with was a charging cavalry routed in every instance (except when the target was Dragoons) and the pursuers chasing them and routing other units they came into contact with in all but one case. Also, enfilade fire seemed rather ineffective but it only came up twice in the game so not much to go on there.
