You could be working in a 50 bit range or a 256 bit range; and you can subtract, divide, multiply, etc. whatever you want to do, or you can use whatever stride you can some up with, 14, 87, 1234344564, 47398573854734834, etc., it won't work because again, you could go around the curve and you won't know where the key lies or where to start your stride function from.

There is truly only one way to take advantage of a stride function; and I stated that months ago. My problem was, I could not create a stride function inside of CUDA. Or else I would have found 130's key already lol.
