Of course there's an average, and of course it could be helpful to know.

The distribution probably is Gaussian.

Unless one knows the standard deviation of the average is extremely high,
then the variables you name are no more too broad to generalize than, say,
adult male height. Even if the S.D. is extremely high, the original poster
could seek averages for simply his locale (and for OEM pads), and this would
reduce the S.D. and no doubt provide useful information to him.
