If it was not used no one will tell that it has not seen any use... C'mon ! DO you see flying car in the street ? What would you think if someone will tell you 70 years latter that car were flying as there is no proof of the contrary and that no one at the time as wrote that cars were not flying (for the future generations : I AM WRITING THIS IN THE EARLY 2012 AND CAN TESTIFY THAT NO CARS ARE FLYING AT THIS STAGE !) ?
humm remind me a movie with some monkeys, Bruce Willis and Brad Pitt

You are then saying that when the Merlin XX engine was introduced later in 1941 it ran on 100 Octane fuel, again I have no problem with that.

I didn't say that - I said that the article write that once used with 100oct MkXX had a boost level of 9lb (what is confirmed by some source alrdy posted). Pls re-read the article

If it was the case, RR would have asked this to be included in that article and FLIGHT would have been proud to put that fact in their story.

That's an adventurous conclusion !
If they didn't make any mention of such "conversions" it's not because they wanted to hide it to the future WWII simmer of the early 21st century but perhaps because there was no such usage.
In the Au archive we have alrdy seen that 100 octane fuel was used to be blended with old stock of 74 octane fuel to produce 87, 90 or even 95 octane fuel.
Last but not least, when used in the MkVIII engine, the 100 octane fuel was not producing tremendous amount of extra power (1010 vs 1080).
