It could be that once you are into the good part you are into the good, or perhaps the heavier, more trash like particles have precipitated to the bottom. And, it would depend on how thick the given strata were, if you could cut multiple stones before encountering the next transition.
How much better if you had 6 sides:confused:? You can only effectively use 1 at a time. If it did act like a combo; but with no clear demarcation, how would you know which was the dominant feature. Over time the stone will thin so if you are using up the coarse side as well; It has the potential to break before you use up the good side.
None of this is intended to tell anyone what is the right and proper thing to do. That is between you and your stone.
