FWWC France '14 scenario size modifier mistake?

[Steel God]

I created that damned chart but how or why I snapped the chalk lines where I did I can no longer recall.  I know that initially we just used the number of turns as the qualifier for SM and we knew in short order that it simply wasn't adequate.  So we created the chart to allow for larger SMs for scenarios based on file size because some "short" scenarios actually had quite a lot of units (and some had a lot of units but not a lot of turns).  Anyway, back then (over 20 years ago) ladder updates were done manually by the Custodians so it was a labor of love to go back and reset the Ladder.  

Anyway - if blame needs to be slung - I'm the target.  I'm sure it made sense at the time.
