Not yet, but I am reading this with interest and I'll try it to see the changes.
I've sent already my customizing excel to many players on the board. It calculates the other relevant specs from weight, balance and SW and also calculates specs change upon adding or removing mass.
It however includes MgR/I calculations.
Anyone interested is welcome to send me the e-mail on private and I'll send the excel.
Anyway, so far I've received enough feedback from players stating how MgR/I of 21 suited their game, or a value close to it (like 20.9). So while it's not every player. a lot players find it really good for their game. But let's say this value might be personal, not necessarily 21, not necessarily close. Still, as it is important to your swing and timing, it's a good thing to understand realize what is the value of MgR/I you prefer, as it is at least as important as your other specs.
Typical MgR/I of TC95 will depend on chosen custom specs option, however TC95 is sligthly stock polarized with thick graphite layup, so it is pretty likely it will have its MgR/I significantly below 21. Now, if you're used to playing with a racquet with MgR/I 21 or close to this value, you'll need more time to adjust to TC95, but why going through this when you can customize it in a way you can play some great tennis immediately? Besides, the added value of compensating MgR/I is you will have to spend least energy on swinging the racquet.
I think I wrote it, but the biggest compliment to my setups is when I had few two hour hitting sessions with a player who otherwise swings with 330-335 grams racquets. He was surprised when I told him he swung with racquets which had 20-25 grams more. So I asked him did he find it hard to swing it. He said he didn't have trouble. He wasn't tired, his swings didn't slow down and what's even better, he's barely playing tennis during winter season, perhaps once a month average. So his fitness level wasn't great eather. Anyway, what can be better test than this? Two hours of pure groundstroke hitting, with much more strokes exchanged than during a match.
For me, this is it, as I'm not super fit myself, if I don't find it hard to swing with 355-360 g setups with 350+ SW and I'm not really fit, then I must have done a good job. And if this is so, no one should be frightened if calculations say he should actually add 10-12 grams at 7'' mark or at the throat. It's important to throw away any mental obstacle in start, any mental rule which might state to you in advance 'ok, this is going to be too much for me', because if you open your mind, try and just observe, you will see how things can be different to what you might believe. Actually pro players specs are closer to rec players physical ability then you might think, but the secret lies in careful customization.
