The reason why I used Skub's Top 1 list instead of Stormfly's Top 1 list, is because its FAR more accurate before 2.0 than Stormfly list, which is mostly based on speculation and "what was the hardest rated level at the time", Skub list tries to show what the actual top 1 progression looked like, and I like it better.
