Exactly - easy to see the mis-entry (putting ZFW in the TOGW line) but the “numbers” should make sense.I can see that happening very easily unless careful not to cross check with the flight plan ( why is the TOW much lighter than the FP estimated TOW given the same fuel and number of passengers? ). It will happen again.
If we were at MTOG, and I saw a VR that was 30+ knots lower than what I was expecting, I would be looking around to resolve that discrepancy, instead of blindly pushing up the power and pulling back at that number.
