I would humbly suggest that this is just another example of cockpit dumb down.
Anyone who has "actually" flown real a/c and not just on FS has some common sense checks based on expected V1, VR and V2 numbers for the a/c type and approx guessed TOW. These numbers sit in your brain as defaults. When you see a number that is 20-30kts different it should trigger an immediate "excuse me, let's stop and re-think" moment.
If it doesn't the crew is either incompetent or so fatigued that death is an acceptable option.
