With a more properly graded 3/4" washed stone (such as a good filter stone ranging between the 3/8" and 1" diameter), you will have a loose drop of more like 75%, but you will also actually be able to get closer to 100% without talking about your subgrade. If the subgrade is sandy, it will not invade such a well graded gravel as much.
