The yellow is probably the most versatile hone out there, that is it's true strength....
As a finisher it is good but not great there are plenty of stones that are probably better (keep in mind the last finish is a personal thing)

Also as you can read tons of threads on just this hone, you will find that it is a natural stone so they actually differ between stones, as to the final finish, so some people who happen to have bought a very, very, fine one will tout it's finishing capabilities, but that does not necessarily mean that the one you get is going to be as good...

As you have already heard above how many laps is to subjective to nail down.... To much of the "Art" in honing is in the hands of the honer...
