While thumbing through an old copy of WRG A&I 1925-1950, I noticed the following in the introduction:

… Other innovations include a one to one figure scale and an arithmetical instead of a logarithmic ground scale.
I am curious from a game mechanic perspective about how the logarithmic scale was implemented. Does anybody have a quick summary of how ground scale worked in older versions of these rules?

4th Cuirassier said this in another thread:
"ISTR a very arcane set of rules developed I think by Bish Iwaszko which used a logarithmic ground scale – 1cm = 1 yard, but 100cm = 1,000 yards – specifically to get around the problem of overscale miniatures."

I think it was the Iwaszko rules that WRG were referring to.

Mike's correct – I actually played those and they almost worked. The idea worked quite well for ranged fire but he had kept movement as simple linear and it was that mis-match that stopped them working fully.

They were even used at a couple of the early national conventions in about 1968/9 if I remember correctly.

I still have a copy somewhere.

Offhand, I would suppose that logarithmic ground scales may show some limitations when the distances among three or more points are being considered …

Mike & Gildas Facit, thank you! That was the tip I needed to track down the info. I was pleased to find the full answer online:
(see page 94-97)
Some interesting discussion about ground and figure scales in general. I located a copy of that book and ordered it for my own little library.

It's interesting that FoW uses a somewhat similar approach to weapon ranges.

"It's interesting that FoW uses a somewhat similar approach to weapon ranges."

That was the whole point behind Bob's question!
