Schaff Tuning Levers - slap tuning

Actually, I think a jerking motion is less likely to break strings than a 
smooth pull. It seems to me it is more likely to break the string free from 
friction, so there is less stress over less time where the string leaves 
the pin (which is where most breaks occur). I've always tuned with small 
jerking motions (hand on the lever, not slapping). I was taught 20-odd 
years ago that that method was more likely to lead to a stable tuning, and 
experience has told me it is so. Of course, the key here is _small_, 
controlled, jerking motions for fine tuning. For pitch raises, a larger 
jerk right to pitch works most of the time, unless circumstances seem to 
dictate a quick jerk down first (too often, those circumstances involve a 
broken string, but it would have broken anyway with a smooth pull, IMO).
