Article about the sf23's development
Talks about how switching away from bathtubs lost downforce but eventually opened up development paths (previously speculated)
The Austria floor was optimization based on the sidepod changes and front wing to improve overall balance
Suzuka floor change aimed to improve consistency of downforce. This meant better balance and drivers can experience similar characteristics corner to corner.

Ah this is why Hulk doesn't want the new package.
Perhaps.. but the Haas is not the sf23: Ferrari abandoned the bathtubs and 6 weeks later had a downwash concept while Haas with 1.5x the wind tunnel time waited 6 months before manufacturing their new car. It can be assumed from the lead time that they, unlike Ferrari, waited to see significant gains in the tunnel before committing to the new direction.
That the downwash concept switch initially cost Ferrari load in the tunnel does however go some way to explain why Haas waited so long in the season to fit the extensive upgrade.. you factor in 1-2 GP of teething issues with a fully upgraded car and they left themselves 2-3 races to make the most of it. From this I'd assume it took a while before they found gains that made up for the loss in load & then enough performance to make a costly upgrade package worthwhile
From Guenther's comments at COTA they expected to gain a lot of laptime from the upgrade, particularly in race trim. What they seemed to have done instead is produce a car that just has different characteristics but not necessarily faster on average, with the new car suiting kmag more and hulk less
There's another, more conspiratorial option. Guenther's "we expected more" comments were publicly to save face that Haas never found the gains they expected, and that the COTA upgrade package was delayed for so long because they never found the expected gains. And in the end they brought it as late as they could but with enough grand Prix left in the season that they may discover/learn things about the car/setup/aero that will inform them of the right development direction. Given how much Haas take their design cues and inspiration from Ferrari it's possible that without Ferrari doing much to their car, Haas had less of an idea than normal. Last year all Haas did for Hungary was adapt their base car more towards the F1-75 for instance.
