Looks fine to me, but I was not that concerned, since it made sense to me that smaller targets would be harder to hit (i.e. below the 1.0 level). Having said that, the linear scaling was too extreme and mortars did seem weak. So, if it now works as you originally intended then there is no problem, as far as I can see.
The individuals that raised concerns both referred to Normandy, so providing a NA 1941 beta may possibly not have been of use to them?
