I'll try to get as close as I can, hopefully without attracting a herd of screaming binary absolutists. The lower the break% of a string, the more reactive it is to minute tension changes. A string at 50% break will take a dimensionally produced tension change (by either turning the pin, or from dimensional changes of wood parts with humidity changes) with only a slight detectable change in tuning. A string at 17% break, given the same dimensional change, will produce a dramatically more pronounced change in tuning. A high break% string has a wide target tolerance, where a low break% string has a very narrow one. You just don't have anything to work with tuning low break% strings. The partial composition and spacing will be different too, but I don't have any real data on that detail. Ron N
