You could monitor and graph the current with one of these USB multimeters

A while ago there was a power meter give away at the club. If someone could
spare you one I reckon they had an RS232 interface with a fancy protocol
that could be pressed into service with some effort. Then you could measure
real power. I would be interested to see how that works out.
