How do you know how much downforce they generate from the floor? Didn't RBR say they controlled the bouncing with their suspension? If they made less downforce, how are they the fastest in high speed corners despite a smaller rear wing?
Because tunnel height is the biggest impact factor for floor downforce. We know this from aerodynamics books and I can also confirm from experience. The inlet/outlet ratio is second and the profile/shape is tertiary impact factor. Now, if you have higher tunnel, but you can have lower ride height, you basically get the best of both worlds and both of these apply to RB18.
Bouncing can be slightly minimized with clever suspension, but if you generate 200-300kg less downforce from floor at 320km/h (which is nothing at those speeds) than you can have a lot less problems. Not sure about RB being faster in high-speed corners so far, at best they were equal to Ferrari. Also, in Melbourne and Imola they had more rear wing than Ferrari and their rear wing is higher camber than Ferrari. Along with larger DRS flap, this is why they have a decent advantage with DRS overtaking.

Imo saying they aren't generating downforce from the floor is far too simpleton of an explanation and I think you know that...They are running smaller wings than Ferrari as well so there's no explanation for their medium and high speed cornering performance if they don't have floor downforce.
As mentioned above, higher camber of rear wing and also larger wing overall in Melbourne and Imola.

Not only that, the tunnels themselves are not the end all be all for downforce generation, a lot of it comes from the central section with the plank. That air is accelerated all the way from the strakes to the gearbox.
"Think logically." How can a flat geometry with no curvature and close to no AoA influence pressure distribution? Is it, in fact, low pressure from tunnels influencing and accelerating the air on the plank? Hint: yes
