And you are right an electronic will pull individual strings at probably +/- 0.2 lbs but over the entire string bed I would think it is more consistent than always being off +/- 0.2 lbs like an automatic drop weight. Then you have the crank machine when calibrated properly and set to 60 lbs it will lock out at 60 lbs with < 0.1 lb accuracy over and over and over again. Ad oh yet as soon as it locks out the string starts stretching so you will have exactly 5% or 10% tension loss. I guess it all depends on what expert you listen to. There is not law that says I can't pull tension more than once. No matter what kind of tensioner you use once the tension is disconnected you start to loose tension.
Plus while there are electronic machines that overshoot, there are electronic machines that don't.
The Stringway ruler is kind of clumsy to adjust exactly the position of the weight on the bar, the ruler is not engraved on the bar, and there could be a better design and method than holding the ruler parallel to the bar to approximate the position of the weight on the bar according to the ruler, no? It surprises me more when this JET method of stringing requires changing tension several times while stringing a single racquet, how can there be great precision in general with a Stringway automatic dropweight, or even greater precision than for an electronic machine, with absolute certainty?
