99% of the time you will "push"

How long you halt for determines the depth of the weld
This is BS. The electrode should always be in the leading edge of the molten puddle for the best penetration. Stopping or backing up is just adding filler but does absolutely NOTHING to increase or improve penetration. The "stack of (pick your coin of choice) look" is for appearance only. Look at any structural mig weld and you will NEVER see this type of weld.
As for the comment of "practice", that is true BUT you have to be practicing the right method.
