Don't forget that in many airlines, "Sim Instructors" are also line training captains who spend half their time in the real world, not just pushing the "V1 Cut" button!
Douglas thats an interesting point, and without wishing to digress too much from the issue at hand I wonder just how many companies have now split the 'Line Standards' section from the 'SIM Checking/Training Section'. Thats what has been done in my own company and I just wonder now what possesses any sane individual to dedicate their lives almost entirely to (as you say) pushing the V1 Cut button, day after day....
