For what it's worth, and I certainly don't want to seem like a know it all, my experience has been to quick bleed brakes conventionally then just walk away. the air bubbles that you can't possibly push downhill(even worse with ape hangers)will always rise to the master cylinder. Just go out and squeeze the lever a few times every so often over a couple hour period.I swear it works, and what could be easier then doing nothing.
If you use this method don't use a bungee or zip tie on the lever; doing so shuts off flow to the system. If you ever need to leave a system open overnight, tie off the lever, you won't lose a drop.
Hope this helps!
