problem with the testing is that I was only recording raw data, so I didn't realize there were differences in the bi-directional averages of the A1 sets vs. the A2 sets until I got home.

I would have needed to figure averages & standard deviation while testing in order to make a call on sample size on the fly.

...Which I suppose are reasonable things to do in the future if I want to have confidence in the testing.
