Its not that hard to line up the music, both on the gross and
then on the frame-by-frame scales.

In fact, even when I did have TC to work with, it was faster
to sync the tracks together using the music on the sound track.

Do-able, but not exact. Good for finding a rough sync. There is a time
difference between the sound hitting the built-in mics. I once tried
this with a tape made from the front of the stage, and one from the
back of the hall. Huge difference.

1 frame of NTSC video for every 36.6 feet of distance to be exact.

OTOH, when cutting between a wide shot and a CU, difficult to
tell whether the sync is exact. Bad news: makes it more difficult
to achieve exact sync: Good news: it doesn't matter! If you can't
tell looking at it frame by frame, the viewer certainly won't be able
to detect it on the fly. :-)
