Anyway, I still feel the biggest floor trick (combined with suspension) lies in the fact RB can somehow bleed excessive floorgenerated DF right before porpoising starts. And aside that Newey for 2022 undertook his usual design-philosophy route by first creating a stable, predictable and widely manageble platform, before throwing everything to it.
Honda ofcourse did their magic truly well on the PU side of things ..
Agree with this, everyone seems to be chasing ultimate maximum downforce and demonstrating they can't finitely control that as it reaches it's peak.
It looks like the "empire state building architecture" shaping on that RB inderfloor plays quite a role in bringing a soft termination of rise in vacuum as car approaches the ground under maximum downward travel, rather than just bounce it into exciting the tyre carcass by crashing into full on suck. Aided by that "mousehole" bleed into the rear part of diffuser geometry to mitigate too high sealing as the edges approach the ground beside the rear wheels.
Just as much influence would seem to be a very stable ride height and roll on front axle, this to provide highly linear feed flow into front end of floor by keep those strakes on entry consistent in relation to ground. It just gives much more predictable numbers to work the diffuser with rather than oscillations in volume to effectively pulse the whole underfloor.
