The rate at which a layer of soil will drain depends on the rate at which the soil below it can absorb moisture from it. Putting stones on the soil below will not alter the rate at which it will absorb moisture. If it is hard and unabsorbent putting stones on top of it will not alter that.
Why on earth would you think it does??
We all know that putting stones at the bottom of a plant pot increases drainage, but it does that by increasing the area that the soil has in which to drip into the air outside. No such effect occurs here, the area of contact between the layers remains the same. You are ASSUMING that it will act like a plant pot, but havenīt thought it through.
