au contraire
in my humble opinion, using the max drift method is proper planning. you have assessed your flight and corrected for the wind. if people make mistakes, then it is down to unfamiliarity and a lack of practice, not indicative of the method being flawed. if you use familiar, you will find using it for real in flight will be doddle.
if you are not convinced with the method, try a few examples, they are within a degree or two and a few knots of groundspeed. close enough for the accuracy of your average PPL student and wind forecast by our friends in bracknell (or is it exeter).
batteries run out on electronic calcs, people lose whizzwheels, but you can't forget your brain. although some students do try and prove me wrong.
and you only get bunnyhops if it's your birthday!
