@ Dan,
Wait a minute!
To correctly follow the pattern set between Levels 2 and 5 (i.e., doubling for each new level) , Level 6 should start at 1,600 points, not 3,200. Level 7 should be 3,200, Level 8 should be 6,400, etc.
Following the correct pattern, it would require 26,214,400 points to reach Level 20 (Guru) status. That's a LOT harder than SodaHead, which only required 100,000 points for Level 20.
