Obviously the model is a bit too difficult for some people, it simply means at low speed you should be more inclined to stop in the event of a problem and at higher speed you should be more inclined to continue..
For info, Airbus inhibit most warnings during the take off roll and only something serious such as a fire will appear.
What if all the ASIs stop working, the attitude instruments all disagree, the altimeters freeze up and you go IMC at 50ft, your diversion airfields all go below minimum, the other pilot has a heart attack and the radios fail.Then you would probably wish you had stopped while you were able to.
