How many Variations of RF97 has Roger played with

From 2012/2013 to present any estimations as to how many variations of the rf97 frame he played with on tour before settling on the current one? Perhaps based on the sounds of the ball striking the racquet, depth, swing speed etc.

Bruh you really think we can tell the miniscule changes in racquets he probably didn't make, especially considering he doesn't have any visible lead tape or weight? From the "sound of the ball??" Dude.

Yes I do brosef! Perhaps I have more faith in the obsessive TT community than you do. Catch ya later

me and my buddies like to sit in front of our tv's with our audio-equipment on.

from the sound striking the ball, we concluded he changed his racquet
times.

true story.

What is function n? Or is it too complex and/or a piecewise function?
That there is sigma notation, which is another way of expressing a sum or series of natural numbers. A common math joke (which can actually be proven by erroneous methods) is that the sum of all natural numbers from 1 up until/thru infinity is -1/12. That is obviously wrong, but very very funny and interesting :)

I understand the joke and what sigma notation is, but there has to be a function f where the sum of the function from 1 to infinity actually ends up being -1/12. Now you got me doing math during spring break...

Ok but that's irrelevant to what I actually posted. The sum from 1 to infinity of n signifies the infinite series of the sequence a(n)=n. This means 1+2+3+...+n as n tends to infinity. A function, unless otherwise defined, is defined on the domain of real numbers and the "sum" of this function (if continuous) is an integral which is definitely different from what I posted. Meanwhile a series is defined only by natural numbers on its domain (discrete). So not only is what you said irrelevant (there're an infinite amount of infinite series which converge to -1/12, or any finite number for that matter) but also you're doing it wrong.

At least you're doing math during your spring break, I wish I had done more math during my spring breaks back in high school.

Oh my God, I know people do things they regret later when they're buzzed but I didn't think it would be like this... I hope my calc teachers don't see this... I vaguely recall thinking something about limits and integrals for some reason, too. And I call myself an Asian. For shame.

Do you know at which point the racquet was finalized? Perhaps at which tournament?
I don't remember to be honest... I do know at Indian Wells he was still trying out some slight variations (mainly string spacing if I recall right but this was a few years back now).

... once he settled on the final racquet early on when still playing a blacked out frame, it didn't change.
Peter, by "127 prototype rackets" you mean a handful of molds that where tested with different staticweight, SW, balance, string pattern, flexibility OR there were really a lot of different molds tested?

I'm not sure to be honest. I started work with Wilson when he was already testing prototypes so I wasn't in the loop early on. If I recall correctly near the end it 2 molds and then various combinations of each. One the current one, and one a thinner beam I think. Again this was a few years ago now and I was just starting out so my memory and knowledge of that time is limited.
