Actually, compressor current draw can be more or less. Depending on the
load, back pressure, over or under charged, etc. It really is a variable.

Instantaneous current mesurement isn't the answer. When the compressor
is running, it always requires the same power. But maybe it will run
less often to keep the set point...

Watt hour meter is the required device to compare for example, two
similar weeks temperature.
