How much volume is lost after compacting 3/4" crushed stone?
The densest packing of spheres is about 74%, whereas a common less compact packing is about 68%. (74% - 68%) / 74% = 8% potential volume loss. A standard specification for careful tamping of backfill is "in 6-inch lifts to 95% of maximum density". In other words, after tamping, there is still a potential for 0% - 5% potential volume loss.
