Now you come here and says its 5 minutes for the IA. There is another manual stating 5 minutes but that was for the IIa i guess. There is so many that use general desinformation and try to using data from other aircraft (IIA) to provide performance of others (IA). Or comparing the best data from one ac with worst of others, or using extra arguments and aproximation much beyond the data to prove their points. The data should talk by themselves with minimal interference of the interpreters.
