The Cataphract trait

[Digby Tatham Warter]

Ok, and now for those of us that do not understand the divine language of RTW codes.

Yes me too I'm affraid, on these parts I would like clarification, if someone could be so kind that is:
and I_TurnNumber > 75
and PercentageUnitCategory cavalry > 10
; and NumEnemiesInBattle > 250
and NumFriendsInBattle > 250
and not BattleOdds > 0.7

I think the first one is not before turn 75????
The second one is that you need to have above 10% cav
The 3rd and 4th being both armies need to be above 250 men
As for the 5th point it's something to do with having similar numbers, but I'm a tad lost, but I suspect it means that they need to beat you on roughly an equal footing, hence your general is more interested as to why he got his arse handed to him when the numbers were even. But what is: and not BattleOdds > 0.7, am I stupid or what because I don't know what it means?

Also do I have to move him to a correct city with said trait?

I think reading through bovi's generous response it also says 100% chance if the conditions are met, so the intelligence of the General and his retinue/traits have nothing to do with it.

Cheers.
