The short general answer is that once the string has been shot-in and been vigorously waxed under tension, I do not expect my strings to untwist beyond a turn or two, if that. So…as it appears your concern may be having to repeat the same amount of twists, it is not only unlikely but what would probably happen first, in response to a “ton” of twists, is that the string would most likely start folding over on itself.
That said, “shot-in and vigorously waxed under tension” usually makes my strings, with a relatively high twist count, behave more like sticks than strings when I take them off the bow. And, in part, I attribute this to using sticky (cake) wax throughout my string construction process and/or prior to twisting to brace height, if I did not make the string. (I use tube bowstring wax as a top coat to reduce the amount of stickiness on the surface.)
To that I would add that endless and Flemish strings are apt to respond a little differently to a high twist count, as the twisting is going to want to migrate under the serving, and endless/continuous loop strings have more serving locations. Anyhow…sounds like you could be in the market for a slightly shorter string and what you have is a potential “back-up” string. I’ve found it is always good practice to have a spare string on hand.
Good Luck and Enjoy, Rick.
