No because after you raise the slurry, you ease the pressure and allow the slurry to break down and refine the initial scratch pattern.
For example you start with 3k slurry but end up with 6k scratch pattern after slurry break down. Because of those properties of J-nats you can pretty much cover 1k to 8-10k range with 2 stones only.
