TBH the reference to reduce the stress on the string is stated by Babolat in the documentation I received when introducing the machine. It does not explain how. I know that the whole point of the Sensor (and the Star 5) is that the electronics "sense" the string so that it can accurately pull and maintain the required tension. But again, I do not know exactly how that works; and I do not (really) need to know.
I am confident that the diabolo is there for a reason and accept the reason given. I 'feel' that the string is under less stress when I use the diablo, and as mentioned, I double wrap the string for further protection if required.
