You only need to click on a field in “Your Input” to begin your stringing frequency calculation.  All other values will be calculated for you!  Don’t worry if you do not have a UTR number yet.  A value will be added if you input “0”.  For “Player Style” you can enter “tour, club, rec, beg,” to automatically insert values.

Value/Playability Ratio is how well the string “plays,” with Natural gut being the best and polyester being the “least” best, so a “factor” is applied to strings to quantify that ratio.
