Is there a more perfect way to do it?....and, is it relevant to a good running model A engine?
Seems to me there is a little wiggle room for getting a good running engine, specifically because the spark advance is manual, and not centrifugal, vacuum, or some other form of automatic adjustment.

TDC
As said , too much rotation in the crank at TDC, Dimple is best.
And Its a Model A, it doesn't much care. Set the timing where you want. It'll probably run good.
An ohmmeter [or volt meter] is good for checking the points when setting the timing.
Set it with lever up at TDC.
Upon starting pull lever 1/2 to 2/3 down and go.
