My testing would be as follows:
1) charge both batteries overnight, and make sure voltage is the same.
2) start car on a 3rd battery
3) install battery of choice
4) connect ammeter in series
5) let car idle with typical accessory load for one hour.

There are still variables,such as temp, and self discharge rates, but this eliminates most. You would need a guino or something that is measuring injector pulses for your reading.
Shooting for 600 miles of range at 65-70 mph out of a vx.
