Mercedes W14

Isn't there also a significant difference in tire wake between the intermediate and extreme wet tires?

Probably yes, because if FW are used then there is more water, denser spray than with IT

Kyle’s analysis for those interested.

he confirms the porpoising isn't caused by the exposed floor surface and the flexing floor, same for sidepods

some here will still say they are the cause

This totally goes against the major reasoning behind porpoising we've been told last season. I thought it was caused by the floor getting too close to the ground or even hitting it and eventually choking. The big floor surface/exposed floor on the Mercedes was told to be especially prone to flexing, but at the same time the car needed to be as low as possible to extract the expected performance out of the concept.
Now we see a Mercedes with a much less exposed floor, but this was never the issue to begin with? I'm confused.

More like it's a coupled suspension/ride height sensitivity issue. Fix the rear suspension, ride height is more controlled, problem goes away

Oh, but why then was the superior Zeropod concept abandoned?

The reason that the media and most forum members kept pushing yes, doesn't mean it's correct. Kyle did a video last year explain what he thought it was, and what he thought it wasn't.

Kyle explains it. To keep the front wheel tire wake further out

Like the other teams?

and in this viddeos he says he thinks that the ride height is whats causing it
mercedes found extreme gains in the under of the car aero but it needs to run at that ride height wich hard without causing porpoising
all that exposed floor or flexing floor doesn't make sense he says

Porpoising was only a thing when team run the extreme setups. If the peak performance was designed to be in that setup bracket, because that's where simulations told them they could get max downforce of all possible designs (even those with a larger but outright lower sweetspot). So obviously that is the MAIN cause, what Kyle refers to. That being said, given the same, say, ride height, it's pretty obvious that elements like floor flex, suspension design ecc. all contribute to exacerbating the situation you unknowingly put yourself into by setting overly aggressive aero objectives.
We should remember how Merc after Spain could easily avoid the problem in some races only for it to come back in others when they were pushing the setup more. They said it was because of bumpiness of the track surfaces and such, and it's partly true ofc, but France was a bit of a disaster compared to their expectations because France requires a softer setup than Silverstone and that forced them to raise the car despite no porpoising. Porpoising's there as much as you're willing to (or had to) risk getting it for performance on the tracks where it makes sense to. RB were smart enough to recognise it was profitable to give up a bit of peak downforce to spare themselves a humongous amount of trouble in setup variability and compromises.

and that it's just a slight design tweak , the zeropods concepts stays the same and now it's even slimmer at the bottom because there isn't the "melted' part anymore
