It was a trap. To see if you actually can read the FCOM.
The RA callout when the "pilot is over the numbers" needs to be 30, as the RA is aligned with MLG that would pass the THR at 34' on proper 3 deg profile. Reference FCOM landing geometry,
On longer (2400+) runways, PAPIs are aligned at 66 ft (or even higher) over the landing threshold due to their longer lateral displacement. That has the potential of forming a habit of aiming far, and in turn creates a need for a personal short-landing technique. And with that second one a hole in swiss cheese is formed!

In the respect of this "tailwind" thread, a good landing to be proud of is one at the correct point and proper speed. Kinetic energy and pavement length remaining, that is all that matters. And not overly easy to achieve. Ok, bins stay closed and coffee pots do not get ejected from housings.
My previous numbers are more suited for 319 with 44t, for commercially laden A320 they better be 5 ft higher, that is true. However
hard landing is something above 1,9 g, no danger of that.
If you are looking for a kinematic explanation of smooth touchdowns, ... as you are the only one to mention the word and did twice already, ... good luck.
