Ahhh. Are these the self same POH's that we are advised to factor because they're flown by test pilots on new aircraft in ideal conditions as opposed to low hour PPL's in clapped out aircraft in average conditions. Hmmmm. You've obviously never read the Beagle Pup POH which looks as though it was written by the sales department given some of the speeds to be used on approaches, which were 5-10 kts slower than we were teaching (and still running out of elevator if the student wasn't with the plot).
