I have considered putting a 2nd, parallel meter in the galley so I can be careful while I am cooking on the electric stove/oven/microwave.
Right now, when the 120vt light goes dark, time to reset a breaker. With the amp meter, I can manage the stove more carefully.
Based upon a previous experience, yes you may see a discrepancy between the 2 meters but not enough to worry about.
One thing I did not try was to use a larger wire to the remote meter to see if the discrepancy disappears.
