 We have cut our treatment times in half. It used to be 30 to 40 visits is what it would take to take care of a disc herniation, and we're half of that now. But not only that, the greater degree of herniation, the worse the problem, we've been able to fix as well, whereas we couldn't always fix them before, or at least not as high a percentage. We're basically approaching 95% success with all herniated discs.
