great how does that improve the racket

It doesn’t, you may like the feel of a proportionally strung racket and that may help you play better but it can’t improve the racket.

and this increases the sweet point of the recket, and is more hands friendly

I don't think so. It does make the DT lower but you can get that by just lowering tension.

ok,what would you say is the advantage of this technique
