For our purposes, isn’t a rough guess close enough? Precision without wind tunnel data at correct Reynolds numbers is meaningless.
It is the guy at the handle and the one tuning the model that gets the trophy. Trust me, I have an MIT degree in Aeronutics, lousy coordination, slow reaction time and never got past an all time career high of one 500 point flight in competition. I treasure that score sheet.
By now, there isn’t much to be discovered in CL Aerobatic science. The pilots are the limiting factor and we need a new generation of ones with razor honed computer game skills to go farther. Sadly, they aren’t interested because model aircraft don’t have a reset button when you screw up. Plus, why spend a year building a model when you can buy a game?
