Hell my accent is different from a Sydney accent and im only 6 hours drive from Sydney . I speak slower for one thing , Country folks arent in a rush . <| sep |> I don ' t think you can extrapolate the lottery odds quite like that . If the odds of winning any individual lottery are , say 1406 ~ 1 in 232 , then 1 in 280 is roughly equivalent to buying a single ticket two weeks in a row and winning first division both times then going on to bet all your winnings on double zero on a roulette wheel two or three times and winning each time . Of course , you can ' t really compare to the 280 figure like that , because 280 is the amount of work you have to do on average before you find a collision . The odds of any individual key you generate being a collision are n in 2160 , where n is the number of existing keys you have to compare against .
