errata to army lists / assets

[Peterloo]

Is there an errata sheet for the architects book ? as it has been out a while and it does contain some howlers.
I say this as during a recent conservation with a mate who plays IABSM - he tore the PBI lists to bits and - he was right. It made trying to persuade him to play PBI a bit difficult.

Points he raised - Sherman - not better than a 2pdr? (I've said this) Unless its a Jumbo when it suddenly improves? - it was the same gun and ammo so why the difference ?

The American infantry get less artillery in 1944-45 than in 43-44 ? - err didn't their artillery get better with the proximity fuse as attested in all historical texts? - unless mechanised infantry -  Wouldn't the merchandised possibly get less as the foot infantry would be supported by Div artillery and be in range where as mechanised might be out of range of its guns.   - though history tells us of the overwhelming American artillery.

If required I could provide a more comprehensive list of oddities in the architects book but I was wondering if this has been done. already.

I know it sounds like I'm moaning (again) but this could just be typos I'm talking about, just wondering before I start amending my book.
