This is indeed the right way of doing it.

I don't get this part.  In stead of storing
you propose to store (at least: that's what I make from it)
  vals:1st min, 1st avg, 1st max, 2nd min, 2nd avg, 2nd ....

This would only change the order of the numbers, not the amount.
So, either you're overlooking something or I am.
