With a more properly graded 34 washed stone such as a good filter stone ranging between the 38 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.
Bulking of Sand. The increase in moisture of sand increases the volume of sand. The reason is that moisture causes film of water around sand particles which results in the increase of volume of sand. For a moisture content percentage of 5 to 8 there will be an increase in volume up to 20 to 40 percent depending upon sand.
