Thruhole soldering- quickest method?

I dont see why this discussion needed to become so complicated.
Maybe you are a factor into that 😉

With paste and hot air theres less precision involved,
You bet.
and hot air being what it is covers more area at once.
And that is a problem.
You overheat areas and parts which shouldn´t.
Not sure why you consider that an advantage.

Precision= more time.
Not necessarily.
Applying paste pad by pad has less precision and takes more, go figure.
To boot, result is unreliable.
Coverage= less time so it HAS to be the faster method.
Not necessarily.
You do it both ways and show us time involved. (YT video).

HOW do you intend to apply paste to each pad?

* stencil?

* one by one using a syringe/toothpick?

Please show that in the video.
 
Hotplate was me. My point, which I didn’t make clear, was you can’t use the hotplate method with TH components, which makes using the hot air pencil a much longer process to get the board hot enough for the paste to flow.
Bottom line, IMO, Hot air and TH components will not be faster than spool solder and iron. 😉
