Yeah, but that was the training command, they were lax
The good thing about that training is the thought process that's instilled. The chart was layed out with time hacks; if you stay on time you know what you should see and at what time -- don't be early, don't be late. My primary instrument was a stop watch.
There was a general rule that if you don't see your waypoints, then turn on time. Problem there is that we had guys flying into a headwind end up turning down the wrong valley. Trust me they never saw another waypoint. All they had to do was count ridgelines.
