Viper, that's a really nice effort, seriously focused... some time ago I was discussing in other forums about real charts of the planes, that were not corrected to the same atmosfere models...
I fly a Cessna 152 and from my early stages of training, I can see the big influence that ambient contitions have in performances like climb rate.
As ambient conditions I mean specially pressure and temperature. For example, before each takeoff I check the forecast for exact data and I get the exact calculation for the Pressure Altitude. If the pressure altitude of my airfield is below the real altitude of the field, that day the Cessna climbs a lot. It's the most common case in winter, with temperatures below ISA (15ยบ) and sometimes pressures over ISA (1013Mb).
The inverse case is a higher pressure altitude when ambient is very hot and low pressures are registered... to the point that if pressure altitude is a lot higher than real altitude of the airfield, it can be a factor that can lead to an accident.
I see that your initial point of view takes this into account, so I'll follow your results with very interest.
I would collaborate with you if I were not so busy with video editing...
