What the program requires is, motor weight in grams to be entered, and you wind to the max torque and record the turns and torque at that point. The program gives you the unwind increment. You then unwind to each point and enter the torque value at that point. There is a separate spread sheet for 10 to 1 and 20 to 1 winders since the unwind and turns are entered in winder cranks not actual turns. I find that F1D motors are a good size to test as they don't take a huge amount of turns and are easier on the hands when they break.
I downloaded the programs and noticed that the formula is missing for unwind. It is turns value divided by 14 in the sheet in the unwind cell enter =a2/14 this is only missing in the first test the other unwinds have the info. I don't know where the formula went but the cell is empty.
