You'd think so but I've found different. All depends where it's stored and what it's near too.

Hope the seams on the cones are ok.

There is every chance that there is a leak from the seam which unfortunately is under the flange rather than behind the strake.

Possible to put a large patch over the whole lot like Nos had done?

Mine is a third of that but I think what they did for Nos is much better. Been told that's the area on the tubes that gets the most abuse from water pressure at speed. When you think about it with speeds over 50mph that water will have some effect long term on older tubes.

Had a look at mine close up before. Doesn't look to bad but I could see where water could lift and course damage.

Really you need to get to the heart of the matter, firstly you need to be absolutely sure that the leak is coming from the seam, I may be wrong but if the leak can't be found with the traditional soapy water method then it could be the seam. It might be worth overpressurising the chamber and trying again with the soapy water paying particular attention to the understrip area where the seam is close to.

I didn't require soapy water, I heard the air coming out while in the water very early one morning. The water was calm like a mirror and everything was still, I could hear something but wasn't sure at first what it was. After a few minutes of putting my ear to the tubes I finally realized what it was and saw very small bubbles coming up the side of the rear cone. Once back at home on the trailer I found the exact area.

Only if you can't get the soap and water on the seam. Otherwise, you'll get bubbles wherever there's air coming out.

Don't get too carried away with the "over" part of overpressure, lest you end up with new problems.
