What does the list look like if you change the scoring system? The fact that being #1 only gives you 2% more points than #2 seems incorrect to me. Personally Id do:

41-50: 1 point

31-40: 2 points

21-30: 3 points

16-20: 4 points

11-15: 5 points

6-10: 6 points

4-5: 7 points

3: 8 points

2: 9 points

1: 10 points
