I have a good overall solving percentage (99%), but my times suck. So of course I am only interested in the solving percentage competition. Will probably never make the top 20 in the other categories.
I just keep playing cause it's fun. And the most rewarding puzzles I have ever done have been my lowest-scoring ones (sometimes I get like 10 points cause it took me so long). It's a neat thing to "salvage" a puzzle that seems unsolvable.
