The initial report on bendy floors looks to have been leaked. Still don't fully understand how it works but apparently......
"‘As in individual pieces of cake around the holes. While driving, some of these pieces are said to miraculously disappear into the underbody on contact with the ground. When stationary, they return to their original position."
"Some teams are getting around the maximum allowed flexing of 2mm by creating a plank which is ‘practically pressed into the underbody’, allowing for more air underneath and thus greater downforce levels with these ground-effect cars, as the car can run lower."

This is pretty well much the equivalent of the variable height active suspension used in the early 80s. When stationary, the car meets all the ride height tests, but at racing speed, it's running lower than it ought.
And the more the air gets "squeezed" under the floor, the bigger the pressure drop (it's related to the square of the velocity), the more downforce you generate and ergo, you have more grip. Which of course, is advantageous, as these cars don't have the same level of basic mechanical grip than under the previous regs.
The engineers can't fanny around with the suspension, so they lower the ride height by having a movable floor. You have to admire their capacity for thinking seven ways of sideways though, but it's not strictly legal. The new guidelines were supposed to have been brought in for this weekend, but guess which two teams threw their toys out of the pram over it...
Oh yessssssssss, Spa is going to be very interesting.
