It is certainly good enough to give you an idea if you need to use the 2mm Method.
The main thing is that it is an easy check that you can do when you adjust your Valves of for some other reason have the Valve Cover off.
It also makes you wonder why the Alignment Marks are OK to use for assembly but not OK as a quick check.
I do not recall the FSM saying that after you did the inital alignment with the Marks that you were required to do the 2mm Metnod.
Perhaps they are assuming during a rebuild new parts would be used.

Generalizing to all cars based on Brian's experience on one or even several cars seems imprudent in the light of the FSM instructions as to how to correctly do it. Comparing them... great... but substituting based "?".
The fact that it is ' an easy check' as compared to an accurate one seems like squishy reasoning.
Are we now confined to what you can remember as compared to what is written in the FSM ?
LOL
The alignment marks are used to be sure the cam is in the right quadrant... and I promise you all this stuff is in the FSM....
