You cannot look at a combat report that used an overboost condition as proof of 100 Octane fuel use.

Let's look at the full Paragraph 3:



"these restrictions" in the context of the paragraph related to the "Duration and Flight Condition" restriction of the engine limitations. For example a pilot may use combat power for longer than 5 minutes or use combat power to climb to operational height in combat or emergency.
I'm afraid this quote does not support your theory.
