... and if the computer's wrong, do you draw the wrong line on the chart?
We might be saying the same thing here, but I am advocating drawing the
line with =no= computer help whatsoever,

That's actually a little impractical where oceanic crossings are concerned.
Routes are assigned based on several factors, and you only get the
information when the flight plan is generated. The waypoints are merely
Lat/Long points. You could draw the whole thing by hand, but you'd be
starting with computer generated data, anyway.

What you're suggesting is actually covered by quickly pencilling the
assigned route onto the plotting chart, and applying the smell test.
