If you read my posting properly I was extrapolating from a CPW employee who said they usually sold 1 or 2 a day, whilst the Oxford Street store said they usually sold 30 a day. I took the low figure and deliberately made no attempt to factor in peaks, merely taking into account the reported (albeit anecdotally) sales figure. So using that I extrapolated to that 500k figure. You can't say it is way too high anymore than I can say it is scientifically accurate, it was purely a mathematical exercise based on the very limited data available to try to estimate a sales figure. Bearing in mind that CPW are the least popular of the 3 retailers for the iPhone it is possible that my figure is way too low. Any information you have to suggest my figure is "way too high" would be most welcome.
