The points you make are valid. However, I don't think the average times are updated that often. I've set hundreds & hundreds of new records and have yet to see my name listed. Even if the stats were updated frequently, the averages would even out over time. As for doing 100 puzzles for few points to equal ten with high points, I would submit that it takes far longer to do 100 small ones than 10 difficult ones. As for the 4X4 puzzles and the 5X5 puzzles, nothing about their statistics compares. You can only get about 350 points max on the 4X4 puzzles while you can get about 530 points max on the 5X5 puzzles.
