Coarser grits are, ostensibly, only faster at removing material than finer grits when sufficient pressure is used. Equal pressure yielded results in favour of finer grits for speed of material removal.

At this higher pressure, we begin to see the coarse hones outpace the finer hones. Even still, there is little advantage in the 320 and 1k grit stones over the 4k, when the greater apex damage caused by those coarse hones is considered.
