Too... long... read... dehydration... kicks... in.

To be honest, I can't afford reading all of it before going to bed (heck I still have a few buildings to think about), but I already have one little comment:
The main trigger to get BattleDread is the picking on weak one, the main trigger for chivalry is the bad odds win one.

Seeing your general kill 8 foes in one battle is a very rare occurence. I checked my log file some time ago and that is only responsible for a very small number of the BattleDread/BattleChivalry results for me, and for the AI it's even less because it's too stupid to charge properly.
Trying to get this trigger is also a pretty good way to risk your general unless he's got a fine armour or some other extra hps

Well, have a look yourself, all triggers are logged ;)
