Nice to see that somebody is using a level for the pitch measurements. Don't forget to apply a correction factor considering the difference between the measured angle and the angle of the development plane. kzbin.info/www/bejne/onybmJqCf9mXfMU

You have wrong measure. Need measure without interceptor.
