Presumably you prefer "alternative facts"?
LOL can't say that's the truth Mike. I'm a WW2 history junkie just like you for over 40 years now. My specialty is the Spit XII if it helps. If you happen to come across Steve Brew's massive two volume history of 41 squadron, you'll find that much of my research fills Volume II covering the Spit XII era. Phil Listemann's book on the XII also has my stuff in it. So no, Alternative facts aren't an interest.
My point is, we've been over this stuff before, including yourself. Your material has been quoted many times. We've posted images showing 51s with 150/100 Octane written in the Data Blocks from the ETO. We've done everything under the sun before to show that factually it happened.
Problem is, folks want it so they can make the game easier, not for some great historical accuracy. I believe the folks at HTC have despite our many attempts to show the 'facts' decided that for game play, giving Spits, Temps, 51s etc 150 octane fuel would not help game play so leaving it as it is, was their decision.
We could obviously take for example, the Spitfire V in AH. Initially we had an LF Vc even though visually it looked like a Vb. It was a beast down low as the LF V was designed to be. For game play reasons I imagine, we got backdated to the early Vb that isn't nearly the performer the LF V was in AH. Our IX has a Merlin 61 when historically the majority of IXs had Merlin 66s. So it doesn't perform as well at the altitudes in AH that a Merlin 66 bird would.
You can go on and on with the "Facts', but combining them with the need for even out the game play seems to be a fact as well.
Here is one of the first discussions of 150 fuel. 17 years ago. There are 25 other threads if you search 150 Octane where folks are making their pitch.
