Well looks like you didn't become the top after all and sold out to p00in

I wonder if that was a 'going broke and not enough BTC held to cover down turns in luck' as per Meni's stats I've quoted many times about PPS

Or could it have been poor statistical analysis of the mining going on with the pool, and not noticing losses that could have been avoided?
(though no pool except mine seems to do this analysis anyway)

Alas the spike in BTC value after you sold the pool seems like the sale was poorly timed.
