The torque and power curves for the Orion look pretty gnarly above 15000 RPM, so I wouldn't draw any conclusions from the data. It definitely looks like the MD2 isn't nearly accurate enough up there. And the flat top on the power curve for file1 says it isn't accurate enough at lower speeds, either. Or are these artifacts from other processing of the data?
