in fact, I think that the compositions / recipes of the strings, especially poly, are so innumerable and varied that it is not impossible to come across a string that is very similar to another.
as long as PP doesn't name their strings with the same names and use the same graphic designs as everyone else, they have the right to do anything.
now, the main concern (and I think the disappointment of some) is that if we read this kind of comparison, and we buy PP references to replace other brands, saying to ourselves it's exactly the same thing , we risk being disappointed 90% of the time. on the other hand, if we say to ourselves, that these are strings to try, to test, and we take into consideration that this is above all superb very affordable strings (the majority of club players will not need much more. . the majority of club players shouldn't be playing with poly in FB!) so, sion tries these tricks quite objectively without expecting to find a perfect clone of luxilon, signum, babolat or whatever, we will be in the vast majority of cases very happy.
I think people who bought PP expecting to get the exact replica of other products 5 times the price are in general disappointed. and it will be normal.
