I seem to vaguely recall your posing a question about armour penetration values on The Other Place a while back. I’ve just downloaded “Two Page Tanks”, and it looks to me as if the armour values are scaled for about one point per 10mm of effective armour thickness. I was, however, a bit baffled by some of the gun penetration values — and I think it’s a good idea to pick a scale that doesn’t need some guns to have negative penetration values.
Anyone who knows me will also know that I can be very boring indeed on the question of armour penetration, so I’m wondering how different your current values are from the ones in “Two Page Tanks”.
All the best,
