'n' is the mathematical variable meaning 'a number' in a consecutive series or sequence, so counting 'a' to 'n' as 14 is not a clue from stan, 'n' could finish as any number... often up to infinity in general cases

interesting thought on the increasing turns, however that changes the resonant frequency, and you can create a step up voltage just by having your duty cycle above 50%, because the doubled pulse frequency will overlap, as described in the TB and patents.
