More idle curiosity, which might be interesting -- were the calculated
averages equivalent?

On those numbers, it should take about a minute to find out.
Replace "," with ";print" each time in the END block of my awk, and
you should get two sets of output which are easily diff'able.
For presentation, you might also like to set OFMT="%.3g" before
printing -- that limits the number of printed significant figures. Or
use "f" for decimal places, depending on the input range.
