Not to nitpick, but this is a little misleading.
20% is the differential between the slowest discharging battery (4.5A) and the quickest (5.5A). In an ideal scenario, all three batteries would discharge at 5A, and thus satisfy your load requirement of 15A. Consequently, the net difference in the ideal/non-ideal scenario is .5A (5.5 -5), or only about 10%.
You would be correct about the 3% drop in the market, and I was not attempting to marginalize your problem. I apologize if it appeared that way, I was just trying to explain the effect. Regardless, it is not my place to say what is sufficient for you and what is not.
If it is your power-bill that concerns you, then you should sleep soundly in knowing that you are not wasting anymore power than you would have where the battery's to have the same output. The slower discharging battery offsets the quicker discharging battery.
Anyhow, Enjoy your ER. We should all be so lucky.
BTW, I am curious. What made you break out the multimeter anyways? Is nice to know that people still test the products they buy.
