I made this spreadsheet a little while ago since I found my old iPod that I used back in like 2010. I believe most of the times on it (if not all) were top 10, so even though there's no pictures of the leaderboards (as far as I know), this should be a good reference to what is a pretty fast time on all levels. I believe a few were WRs as well. I also included my new times as a comparison.

Most of my new times are slower, but they are recorded.
