By using EAS, all you have to adjust power production and you are in the ballpark for the Indicated Airspeed you should see performance.
I did it that way so it would be useful for the game. If you know the PEC, it is not hard to have the spreadsheet convert EAS to IAS directly.
It takes a little time but it can reworked for any aircraft.

But your graph Crumpp bears little resemblance to the RAE chart. Your chart gives the 109 a better sustained capability whilst the RAE chart gives the Spitfire a better sustained turn performance ?

Crumpp chart:
Dont see any parameters/conditions/assumptions used on your chart either Crumpp
Who is right RAE or Crumpp ?
