It is the dumming down of flight training to the point that when the numbers are not there they crash. ( Such as airspeed indicator failure. )
That is a good training regime to cover up the the AI and get a pilot to fly a circuit by power setting and feel.
Also to land clean and with full flap at different speeds as well as steep and flat approaches.
A PA28 can be landed at 60 kts as well as 100 kts albeit your stopping distance will be far longer.
You can flare at 20 feet 10 feet or 2 feet
