Most people wrap cables incorrectly. If you wrap the able around your arm, you are unwittingly introducing twists into your cables which are not good for them long term.
There are other methods, but I have used the "over/under" wrap for many years (a habit I picked up in my pro-audio days). I've worked with cables that were 10+ years old and unwrapped and rewrapped on an almost weekly basis that have zero twists in them. Before Tesla replaced my entire Mobile Connector (due to a bad NEMA 14-50 pigtail), I had zero kinks in my 2YO cable that was uncoiled and recoiled 3-4 times per week.
