Rather than sorting the list each time a new point is added, I suggest also using a binary search for where the new point should go, then inserting it there. That's much faster than sorting the entire list (if the list is large). A simple User RPL routine which performs insertion into an already-sorted list is here: https://www.hpcalc.org/details/6877
