That "Toy" as you call the KAW meter has quite a few reviews online
stating accuracy is very, very good. I suspect your instrument is off,
or your frige on the bum, since my tests, done on several friges
conform to my utility bill at $0.13 kwh. Even an old unit I have, came
up after a 4 day test at around $11 a month.

You claim $11 per month, so that's 11/0.13 = 84 KWH over 30*24 hours, which
would as an always-on average load rate to just over 100 watts. A big
refrigerator does not average 100 watts. It's more like 300 watts when it
runs, and typical duty cycles with an icemaker are mostly running.

And don't forget my little gem of wisdom that your indoor refrigeration
cost is twice as bad as your refrigerator electric cost when you are air
conditioning, because you're pumping that heat twice, not once. Once from
the refrigerator into the kitchen for $1/day, and again from the kitchen to
outdoors for $1.25/day. So the accuracy of your outlet meter is not really
the point, because it doesn't measure the true marginal cost of the
refrigeration per BTU. This is one of the huge holes in the Energy Star
claims.
