I would estimate a 15 turn motor will run 15/19 of the time as a 19 turn. (a fraction) get it?
An example may be that if the 19 turn ran for 9.5 minutes the 15 turn may run for 7.5 minutes.
Yeah, fractions, got it. Is this something you just came up with or do you have anything to back your estimate? I'm just asking because if I use your formula, a 6T motor would last just 3 minutes. That $ux.
