Calculator for final tuning using MgR/I

[MattHeup]

I made this for myself while starting to explore what MgR/I has to offer. The idea (as far as I've been able to gather) is that you can use MgR/I as a last step in tuning the weighting of a racquet, by finding your ideal swingweight first and then using MgR/I to find a weight and balance that works for you.

The calculator will take the swingweight and MgR/I that you want, and show you all the possible combinations of static weight and balance that would give you that MgR/I, given the swingweight that you put in.

Seemed like it would be useful enough to those that believe in MgR/I that I'd put it here, regardless of how useful the metric itself may be. I haven't tried tuning using MgR/I yet, so I'm in no position to say whether it will actually do you any good tennis-wise.

Apologies if someone has already made something this. If so, I couldn't find it, only calculators to find MgR/I from basic specs, not the other way around.

I’ve got to think more on this but actually seems pretty cool.

one piece of feedback: why is x axis in kg and not g? X axis should be g.

Looks good! This graph is just showing all possibilities, right?

What would be great is to get a racquet customization tool that shows you how to change a specific parameter without changing MGR/I. Example: I want to add SW without changing twisweight, nor MGR/I. RacquetTune app on iOS is very nice but it doesn't show MGR/I unfortunately.

Fixed! I tried to do that when I was making yesterday it but screwed it up in a really dumb way and couldn't find what was wrong, so I just went with kg because it worked. It's in grams now.

That's a great idea but I have no idea how to make that happen

I've been playing with this lots and wanted to thank you, I've found it really helpful.

Very cool, thank you!

This is super cool! Anyway to incorporate target recoil weight into the tuner? I'm interested in targeting both mgr/i, recoil weight, and sw

If you want to increase SW without adding TW, first add mass at 12 o’clock to increase SW. add the original weight to the new weight and use the tuner with original MgR/I and new SW inputs. Find the new weight on the graph then look to the y axis to see the balance you need. Add weight to the butt to get the balance you need. The only caveat is when you add weight the weight in the graph changes. Therefore you have to play around with it. This is just one was I’m sure there are other ways like adding mass near the COM but that might mean you increase TW.

EDIT: Placing mass at the tip and butt also increases RW more. Where as placing mass at the COM does not but TW goes up a little

Adding mass at 12 is going to lower the MgR/I value. I would suggest only adding half the mass you intend to add to the racket because you’re going to have to tail weight the racket to bring the MgR/I back up.
