I have some questions about winding conditions. (if these value were correct)
* Why was it same pitch of 3R3 and 4R7 but wire diameter different ?
* What data did you refer to dicide the pitch ? (Because the pitch of red value are under Max diameter of catalog value.)
* Why did you change the pitch in same wire ? (ex; 680&820, 331%471)
* Why did not you increase the tension in thick wire model ? (ex; 3R3~150)
* Why did you set the same tension as 180gf in 470 ~ 181 ?
* What data did you refer to dicide the tension of 221,331,471 ? (Because this tenison was bigger than safty tension of Nittoku EG)
