I had previously created a spreadsheet to calculate the swingweight and others based on extra weights on the racquet. Swingweight Calc Spreadsheet
I took it one step further and created a racquet spec auto optimizer using excel and solver.
It works by setting target parameters and allowed...
Advanced players care about recoil, and here’s why. Swingweight, twist weight, and recoil weight (also called ‘hitting weight’) all measure the inertia of a racquet along different axes or planes. Recoil weight shares the same plane as swingweight but its axis is the balance point (vs. the...
Recoil weight, the polarization index, and MgR/I are different measures of racquet polarization calculated from the same variables of weight, balance & swingweight (SW):
THE FORMULAS:
Recoil Weight = SW - (wt. in kg. x (cm balance - 10)²)
The Polarization Index = Recoil Weight ÷ Weight in grams...
