Thank you for clarifying! That makes total sense and echoes my own experience (even at the lowly 4.5 level...).
As anyone who has spent time/money/effort testing countless weights, balances, strings, tensions, grips, etc. to find what works for them realizes - these specs don't fall from the sky or get emailed by a Wilson engineer. A player has to put in real effort to tune and tweak what works best for them. I string/customize for many friends/acquaintance players - some ask about my specs/setup and to duplicate it for them. Even at my tennis gnat level, I only answer in vague generalities - unwilling to give away the "edge" (however tiny lol) that I worked to find.
Usually its easiest to deflect spec requests by (honestly) explaining that there is no perfect "Platonic form" of racquet/string/setup/spec... Rather the best compromise one can find for their own game! To think that Roger's setup is also perfect for you seems unrealistic. I understand there is a cool factor to having the same gear as the pros, but often ppl take it too far. Do you really think that wearing Usain Bolt's shoes will make you run faster?!
NDA?! Where's the motivation for P1 to do that... Makes far more sense to respect specs as players' owned IP and let them make the decision.
