The magic number was 2000.
If you had less than 500: Oh, you're in big trouble. You owe me 2000 strokes right now, followed by 10 edges, and 15 smacks to the balls.
501-1000: You owe me another 1000 strokes and 5 edges.
1001-1500: Give me 500 strokes and an edge.
1501-2000: Good boy. Stroke however you want and come and worship my legs. Mmmm, that feels good.
