First of all:
You’ve got a choice depending on the hold
Light aircraft you wouldn’t fly 6 mile legs but a timed hold.
But for the sake of the discussion, entry’s are at pilots discretion.
There is no ‘wrong’ entry, just a more correct or more convenient one.
So when the hold is 6 mile legs this means the inbound course is 6NM.
This doesn’t include the entry.
So you fly the 1 min entry prior to turning, cross the fix then turn and fly 6NM outbound +/- wind correction.
