You cannot 'calculate' drivetrain loss.
You can only make an estimate.
What was the power measured at the wheels? (I see a lot of numbers with descriptions all in czech or something).
Only the measurement at the wheels has some meaning although different dyno's give different numbers (also due to different means of measurements). Rwhp is usually within 5-10% accurate.
