A variation of this that I use is to use the tips of shears to crimp the slightly moving joint before tapping.

Since the piece has cooled considerably at the punty end as you are focusing on finishing the top/lip etc., you need to flash heat the punty in the glory combined with bench torching the bottom of the piece several times to get it back up to the heat you want.
You know you have the bottom warm enough when you have the piece barely moving on the punty. Now you are ready for the final flash and the knock off.
Using this (warm enough to be almost moving) technique I just touch the desired break off point with the tip of a butter knife, turn 180 and touch again and rap the punty with the blade of the butter knife. Presto, nice breaks and no breakouts of the bottom.

Ignore the warm enough to move protocol and you can be assured of poor breaks.

This is all bringing me back to a great Larry Bell quote:

"A good craftsman never blames his tools. He blames his assistant. "

How often do you typically get to work with glass Franklin? As Pete and others have mentioned, a lot of this info is very specific and whats really important is time and practice more than anything else. With enough time you will develop a feel for the material that will carry you.

Ha! Develop a split personality! You may be concerned with your behavior.

I still blame my parents for everything. Give that a try.

But to do the same thing over and over again and expect a different result is ......dotishness. Sometimes I just want to talk to someone.

Repetition is only dotish if you dont learn from the failures. 10,000 hours is a long haul and it is absolutely accurate. Just trying to help. Keep in mind that almost everything you learn torch working applies in the hotshop as well. For the last few years Ive been working on goblets and vases on the torch and I apply what I learned in the hotshop to those every day.

The success of your punty is as much to do with the quality of your jackline, they are interdependent on each other.
You kind of have to solve for the jackline to be a weaker join - but only slightly so, than the join at the punty when transferring. If your jackline is thick or not well defined, or the wrong temp, you will end up overcompensating by making the punty stickier than it needs to be. Working alone makes this all the harder to resolve because its trickier to manage the timing of the transfer - but persistence will get you through it.

Talking

Quite correct Peter. If I have to fiddle too much with breaking off the piece to transfer , the punty gets angry.
A thick bottom solves lots of pain.

I put a foot on almost everything it gives you a lot of room for error. I have to make cups to remind myself how to make a real punty
