German AI buying behaviour

[Brian61]

Don, what percentage chance is assigned to an x1 or an x2 radio code, and does the AI buy routine have any way of taking theatre into account? The reason I ask is I keep seeing things in various OOBs showing up a bit early, like for instance, a 6/42 Knightsbridge box, North Africa and the AI is showing up with Valentine III's when according to what I've read, the biggest armor threat during the battle of Gazala the British had was the Grant. Earlier in the same campaign the Grants appeared about two months earlier than historically.

Is this one of those scenario vs campaign needs things, or maybe just too complex to 'phase in' a piece of equipment? By 'phase in' I mean a unit would occur multiple times in the OOB with different rarity codes depending up the date.

I realize this is treading on the nitpicky ground You all have done great work with this game

Thanks,
Brian
