One question I have about both your solution and mine is how easy it is to vary the time drastically by changing the size of the hole. My intuition says that too large holes behave much differently than smaller holes and if you want a drastic 5x difference in speed you might get into this “too large and the sand sort of just rushes through” behavior.
