+ 1 on this. Keeps em from tangling. I’ve read Hollywood gaffers (the guys who do the electric rigging) can get fired for failing to do this. They run so many cords it really speeds things up. I had a 50 ft tangled up home compressor air line from me using the climbing/sailing twist coil technique and disciplined my self to do this and after the twist got reversed the difference was amazing. Try it.
Good on you for not tolerating gonked up extension cords. Any way that allows you to store them without tension and be able to be thrown out without tangling is a good way.
As a some-time Hollywood gaffer, I can report that a feature film crew deals with everything from thin little charger cords for small LED lights and very small audio and video cables to hundreds of feet of 0000 ("four-ought") power feeder cables.
The cables must always be stored in an orderly fashion and be ready for use at any time, without taking time to untangle. 'Over-Under' cable wrapping is usually used for smaller cables such as audio and video and usually discouraged for 25' and 50 12/3 120V AC extension cords and larger. But, it
can work for 120V AC extension cords and beats having them all tangled up.
The object of the of the cable wrapping protocol is
always to coil up the cables without stored tension. That's the object of the daisy-chain wrap, which of course can be avoided by just using 50' or 25' cables which easily and quickly be coiled in a circular pattern.
