Is there any downside to tying like R. Shachter?
R. Schachter has derived a sheeta designed to fulfill two differing opinions on tying in the Gemara – i.e., do we tie 7 to 13 groups of 3 wraps, or 3 groups of 7 to 13 wraps. Each position interprets the gemara in opposite fashion and are thus self contradictory. He is surely aware of this and may nevertheless hold that it is better to try to reconcile them in practice.
