Did you include all files of any kind, not just yours?

All files?

    Average = 75.4519
    Std_Dev = 23.5872

Still way, way wrong.

Why would you ever think it's 80 and 40?

[serhat]

Of course the numbers will be different for others but many systems have a lot common files. I have linux & windows on my laptop so maybe that's why I have a high StdDev. Your mean is similar, but StdDev low compared to mine. What do you have on your laptop?

[CarolineW]

So are you saying you never really thought it would be 80 and 40? If so, why did you ever say it would be?

[serhat]

No, I did, it is on my laptop. I was not expecting your level of StdDev.
