If they manage to make it feel good then I give it a good chance. I often play a Graphene Prestige Pro at 325 grams with extra weight on 3 and 9 and it plays suprisingly well, it becomes a total different racket:)
It can also be manufac. bias. Not sure it has to do with the paint. But if it does; you basically have 4 ground layers of paint + 4 top layers of paint involved in measuring thickness, that is def. at least 1mm.
