Great stuff. I have found that with the tendency to do larger maneuvers we do them a lot higher and it is a lot more difficult to determine what is level and what looks like level, etc. I can get you some GPS altitude data but I don't know how good it is. It is also difficult to find a place inside the plane to measure static pressure. From experience, I'm guessing we hit 800 feet at times.

Can't wait to see your drawings.
