Gosh the team whose car was designed to flex the floor but isn't working too well is the shocked that other teams may have floors that flex successfully.
Why else did they want a second stay ?

Because they had flexing of the floor further out towwards the edge which would cause the floor to seal. A side effect of their zero side pod design as there is less support.
The new tests are for chassis flex near the central plank.

I wonder how you test something that doesn't happen until the car is in excess of 160mph, especially something hidden away underneath the car?

It'd be interesting to know how they do it. Both teams and the FIA testers.
The tolerance is 2mm so there must be a defined way of measuring it already but as you say it only happens under certain aerodynamic load.

At the front of the floor yes, but I don't understand how it can be sprung towards the rear.
Do you have any links?

Maybe the springs are being used to maintain the air gap between the floor & the ground, whereas others are using the whole car. So that when the suction breaks the release is violent & induces the porpoising (Mercedes) but using springs it's far less violent (Ferrari & Red Bull) as they take up the flex. No real idea just hypothesising
Because they designed their floor to flex within the regulations whilst others have somewhat skirted them and thus potentially gained an advantage?

Hence why it needed massive reinforcement and metal stays .

But if this was the case then why did RB object when Mercedes wanted to add an extra strut at the rear of their tray to stop it flexing further as they thought that was one of the issues.

It was Ted Kravitz, on one of his post race review who mentioned it two races ago. Pointing into a bin of springs, only for the mechanics to pull the bin out of view, and the screen across the front of the garage to stop either springs or car being caught close up on camera.

Makes me start to wonder whether some teams have indeed been straying into Lotus 88 territory.
I've a mental picture now, where the floor (or parts of it) aren't integral (or rigidly fixed) to the main chassis, which I understand that it should be. So you've got the bottom of the tub, and then I'm thinking almost like the coil springs in a mattress between that and what appears, from the external viewpoint, to be the floor.
If I've remembered some of my dynamics lectures correctly, that would certainly work in damping out the vertical oscillations that result from the variable airflow through the venturi.
Might be barking up the wrong tree here, but hmm...

If it was a couple of races ago, I assume they will be talking about the damper placed towards the front of the floor

Maybe it is linked to the chassis flex further down?

He was saying it ran the entire length of the car, for those that were using it. A sprung floor, seperate from the main floor.
