OK as a devil's advocate, I have more comments.
A great design principle is, build from the fewest, strongest possible components.
This principle may or may not be very well aligned with your renderings. I am not sure it is.
But it is a useful principle, if coupled with the other most important things for your project,
for example, "lightest" or "cheapest" or "more impact resistant" or "easiest to assemble."
Of course, common sense plays a role too....
With 20-30 bolts, you could float the surface on bolts and not need the stringers. With stringers, you could dispense with all those bolts.
With a solid base made of thick plywood, you wouldn't need to worry about knocking a corner of the table and throwing it out of line, and the base would be about the same size as the top, so not much more storage space needed.
60cm is a good width.
Finally, a devilish comment: it's more fun to copy and paste in CAD than to drill and align 20 or 30 bolts.
Yes, you're right on many aspects... I'll have to do some redesign. I'm kinda new at this, and this is just my second "virtual" table design.
But I see that I'm over complicating... From what I've been seeing in other posts (and I've seen a lot of them...), I can easily lose every other bolt (total of 6 on each side) and still maintain design intent. But I'll still make the holes, just in case I want to give a board an un-progressive rocker line.
As for the central stringer, I saw a good solution that will prevent me from making a new rocker template each time I want to make a new board. And adjustable height stringer just a few cm long. Just enough to deform the rocker table top. It's not hard to accomplish and saves some money in the long term (can't find the link right now, but have the image in my head).
From what I've been investigating on shops nearby, I'll spend something like 20€ on wood for the table, max! The most expensive stuff will be the fasteners...
But ok... it's a one time cost.

But if the computer says it will work....
It's just a preliminary design also. Some channels conjugated with rocker and concave. If I take out the channels, it's jut a regular board with simple concave and rocker, so there's not much science there. I just want to make it more stable without fins.
My main issues, since I'm new to this stuff, will be flex control. But as said above, still investigating. I'll have to try out a first board attempt, simple, low cost, to check how it works, and then re-design it structurally, regarding wood thickness, fiber laminating, etc.
Once again, I may be over complicating it. But so what... it's a hobby! I like to complicate it!
