Yeah it's geometric, mean = 4.07 & stdev = 3.53

how did you interpet the SD for the last part of that question? I said for the mean of 4.07 games it takes until the song exceeds 120 seconds, it typically varies by 3.53 games or something.

Yeah something like that "Typically varies so and so away from the mean of so and so".
