Yeah, and what long and complicated words the guy used like  
`interpreting' and `participant'! I bet your brain hurts from reading  


PS: the calculations below are oversimplified -- it assumes an  
`average' key cracking rate, and doesn't take into account whether a  
given participant puts more or less effort into the project. It's  
better to take your daily keyrate from the stats page and divide it  
by the number of remaining keys, which is (1 - (% complete)/100) 
*2^72. Now that's almost PhD-level mathematics!
