And a bit more explanation why 1 & 2 are prone to occur

It is very possible to cause a range 1-3 over-rev situation without ever having done anything wrong. When you run WOT (wide open throttle) up to the rev limiter and the ECU cuts you off, then you dump the clutch to pick the next gear, there's so much intertia within the engine that the revs continue to climb. That's why you'll see just about every used Porsche that people are looking at come back with Range 1-3 over-revs, but often for very short periods. For example, you might see just 30 "ignitions" at Range 3, meaning just 10 Revolutions. That's not caused by somebody missing a shift because a 5-2 money shift is going to record much more.
