(.32x980.5x32.4)/517.92=MGR/I of 19.62
Can anyone confirm as I am terrible at math and have done my best with what I know or have picked up on the formula used to find mgr/I ???
Now how much weight will need to be added at 7" to get to 21? Can anyone help with this part??? Sorry to be such a pain. It's an interesting concept but I am having trouble following it.

The results are wrong! I'll assume your swingweight is
326, Mass is
340 grams, and balance is
32.4 cm.
With calculator, first do 20
times .34
times 32.4, then
minus 34 because 100 times .34 is 34 , then simply
add 326. Answer is
512.32
Now do .34
times 980.5
times 32.4
divided by 512.32. Answer is
21.08 So you are already within the optimal range !
