This is known as the "Labrador" landing technique.
Not after the place - but after the dog, hanging its head out of the side of a moving car, ears flapping. For Pilot's its especially effective when wearing a leather flying helmet so it can flap in the wind like ears.
On a more serious note....
Introducing this kind of random technique to someone who already holds a licence sounds
very odd to me.
Your visual senses and equilibrioception (inner ear) senses are quite focused in the final moments of an approach. How much time passes between that initial sense (from visual and vestibular systems) of a wing lift from a gust and the physical correction with the yoke? Its miliseconds, and its instinctive. By the time your at 100 hours - as you are - you will trust your senses and automatically react accordingly.
If you havent been trained in this 'labrador' technique from the start then the last thing you want to be doing now is waving your head around on short finals, creating conflicting information to your senses.
Otherwise the next sensation you'll feel is likely to be the shudder of the 172 off the side of the runway and you wondering how you got there.
I would be really interested to hear this instructors logic!
