I don't think there is a problem with the whisker biscuit rest itself. There can be a problem if people won't set it up properly. The rest and the bow need to be tuned together with the correct spine arrow in order to have good results. The shooter also has to execute correct form because the arrow is on the bow untill its free of the rest. If a low brace height bow is critical of shooting form the whisker biscuit is even more critical. If you torque the bow the biscuit will throw the shot right where you pointed the bow last. The whisker biscuit can teach you alot about shooting your bow and you won't drop your arrow while learning. Good luck hunting!
