Cough.
Post the section of your AFM that discusses an all engines operating flap retraction height. I've had a bet accepted for a thousand pounds that data did not exist for a clean climb below 400 feet and I've posted it. From the AFM. I'll directly issue a double or quits to you if you like that what you do on a normal departure does not come from your AFM. I'm going to suggest it comes from Flight Safety.
Are you up for the double or quits? Are you sure what you are doing is what the people who built the plane think you're doing and that I'm nuts?
If so, bets on.
