That's total BS IMHO. Here's how you do it, followed by soldering & shrink tubing.

I've used that for decades.
I was calling it the wrong name. I called it A&P or NASA style. (IMG:style_emoticons/default/av-943.gif)
They just appropriated it from someone else!

I've tested three splice spans (20,16,14) for both resistance and failure.
No difference in resistance on a Fluke 87 and they never failed at the splice when the wire was shock tested to breakage.

In 30+ years I've never had to re-do a splice done this way.
For the last 8 years I have been using type 2 heat shrink with the glue lining.

Once you get "good" your spice will look like you just added heat shrink to a wire.
Almost no diameter change.
