No offense, but I do not read the Babolat labelling the same way you do. For me, they are using the same basic envelope/pouch for 1.35mm/15L gut and 1.30mm/16 gut.
The way I read their recommended tensions, 53 lbs is the max for 16ga and 70 lbs is the max for 15L ga.
Am I wrong? This seems way low, but that is what the information on the package says to me. And like you, I string above these tensions, but when you read the label this way, what does Babolat mean?
What is actually in the package is printed below these suggested tensions, and the particular package you took the photo of was 1.30/16 ga.
Thanks for your viewpoint; I have always enjoyed reading your answers.
