You're right, that' show these things work. But they do this in fairly
short time frames, with, at least in AutoTune, some smoothing effect
(change based on last 3 or 5 readings, taken every 5 or 10 seconds). Tuning
by hand is, in my opinion, even worse, as far as your question goes. By the
time you've seen how something 'was' going, you're minutes away, usually.

A premise of these utilities is that the machine is very fluid, it's
constantly changing, and any guess for how it should be statically set will
be wrong most of the time.
