I had charts similar to the ones you posted that I issued when this was being standardized but I cannot find them ATM so I cannot say if these are close or not with just a quick read through. The couple of mortars and guns I checked seemed OK but that was only a couple of each at random.
As Andy said these were guidelines not carved in stone. If something, for example, like a rocket was known to have a small HE payload that would have been manually adjusted.
