Just remember why we are following the "normal" procedures during autorotation pratices:
To establish some kind of "reflex" when the engine quits in real life.
In most cases, you will not go for a standard straight in auto out of 750/1000 ft AGL, but you will find yourself in a position where you have to turn/extend or shorten the glide.
So stop discussing about what would be "easier"-and do, as the instructor said, because thousands of pilots have been doing hundredthousands of autos that way-and some of us had to prove that they can do it in "real life", too-and it worked for most of us.....
