Please read carefully:

If you choose 2 dozens to bet on then eventually the losing dozen will have a huge streak and you'll lose everything, this bet is designed to counteract against the losing dozen by alternating from 1 dozen to the other always keeping a chip on 1 chosen dozen and bouncing bets from the other 2 dozens to stop the losses better, dozens don't like to chop from 1 to the other for too long, but can sit in one dozen for a lengthy time.

As you can see in the video
I always keep a chip on the 1st dozen

Best way I guarantee
