Landing on the numbers is the culmination of a precise approach and a precise landing.
It is what we strive to do ie to be accurate.
Landing on the numbers means we have the full published lengh of the runway to stop on maybe not quite as important in light singles by certainly important in large heavy aircraft.
Hence why the holiday jet is plonked on rather than going for the smoothest touchdown.
Get sloppy and one day you will find yourself on a minimal runway touching down 2/3rds down it so aim to get it right regardless of runway and take a pride in doing so.
