From a well known instrument instructor and writer:


I don't believe this is true. Follow the instructions WHEREVER you
start the miss, and there is no need to fly to the MAP, UNLESS specified.

Standard challenge of mine for many decades: Find me an approach
anywhere where executing the miss as stated will get you in trouble
if you miss "early" inside the FAF.

I've no objection if you DO it to feel good, but I don't believe it
is a REQUIREMENT, built into the system.
