That does not mean every airplane on the field was using 100 octane.
You have
18 squadrons by that list by sometime in September.
You only have 16 squadrons thru August.....
You have 12 squadrons in July.....
10 Squadrons in June....
9 in May......
5 squadrons in March....
4 Squadrons in February....
Seems a much more realistic deployment schedule for operating the engines at 3 times their design capacity.
