1 piece 50/50 was a Babolat stringing pattern to save the wear and tear on natural gut strings weaving through all the crosses from top to bottom. It also created a means of stringing all rackets one piece by centering a set of strings on the racket. The big problem was the long sections of string from where the mains ended to the center of the racket. Babolat recommended pulling tension on little higher on the first few crosses to account for the tension drop.
I have the ability to drive people crazy, not sure if I was born with it or I learned it but I'm damn good at it.
