For those that don’t want to change the standard tying method with Lavan. This also is good as it meets the Raavad’s requirement of no less than 7, no more than 13.
In Chassidus/Kabbalah this pattern is also very popular since the AR”I prescribed this ratio but with Chulyos. The AR”I in Shaar HaKavanos apparently allows for Chulyos to be broken up so that double knots can be placed in between, making for 7-8-11-13.
