It is 40 minutes but you only get 50% of your flight hourly rate. So 22 hours of boarding pay equals 11 hours of flight pay. But like I said, the average is actually lower than 33 legs per month because in my 2.5 legs per day average I excluded international trips and 90%+ of those trips are 2 legs per 3/4 days depending on how long the layover is.
