The anacodtes are not that informative. All latex sealant are inconsistent with inner tubes. Sealants for inner tubes actually have a different formulation. The sealants above are for tubeless tyres really. I only use a sealant on a tub to fix a small puncture not as a preventative measure. When I tried that success was mixed, so I carry at least on spare tub.

Also latex sealants on tubs with latex tubes are not a good idea unless you keep them inflated. If you don't your tube can stick together and that's bad for the tyre.

Yeah, that's why I didn't rely on anecdotes (like the myth about sealant only being for tubeless tires) to decide on Orange Seal. It was one of the top performers across butyl and latex tubes during this test conducted by slowtwitch in 2014.

the problem is with the test, they take range of pointy things, and push them through a stretchy thing...
Three puncture sizes: 1.2mm thumb tack, 1.7mm nail, and 2.2mm nail
...this is where they go wrong, the resulting hole is not the maximum diameter of the pointy thing

the stretchy tyre (and inner tube if present) will have only a tiny puncture, because the stretchy material can simply deform around the nail and then relax back when it is removed

in the real world, most of the punctures in my tubs seem to be produced by glass/similar pieces more like a blade than a pointy thing, the tyre/tube do not deform around this, they get a linear cut, this is much more challenging to seal

Agree... But orange seal has been very successful for me in sealing those kinds of punctures on my tubulars as well.

It's easy to poke holes in any test (pun slightly intended) - but at least they made an attempt, and one that I think provided a very good baseline. In the last ~3 years of riding almost exclusively tubulars, I've not had any reservation in taking off with just a container of OS and a pump in my pocket. In that time, I've only needed to call a lifeline twice. One of those was (foolishly) riding a Veloflex Carbon on chunky gravel. The last one was glass and me accepting that I should expect a shorter life out of my Arenbergs if I'm going to play on gravel every week or two.
