Ok, the only problem I had with that is if I do lets say a teardrop entry like i said earlier, if i fly outbound for 4NM it will probably take me a lot longer than 1min in most single engine trainers. When you go to make a turn back to intercept the inbound course you really would not know how steep/shallow to make the turn so it can be relatively continuous, If you use the 1 minute outbound for the entry then it should be a consistent and continuous bank standard rate turn back to intercept the inbound course. Also when the 4NM is depicted on a GPS approach plate it usually has a line on the outbound leg at the end of the leg, my interpretation is that this is the point in the hold where you should be 4NM from the fix you are holding around, not at any other point during the hold including the entry. Not sure what others think, I just need a little more convincing evidence and reference before I teach it a different way, plus my method works and I know many others that teach it my way too.
