Or is it misleading and I should not exceed 70 psi?
I tried a second sealant recommended by a large bike shop and it had the same behavior.
Schwalbe is a larger provider (bike tires, for example). Their kit for switching to road tubeless worked fine (rim tape, valves, sealant, a special solution for seating the tubes, tire booster – all rated for road tubeless). But didn’t work for sealing the hole. Neither the other sealant.

Just think about car tires: you don’t need any research to find a sealant that works, any small tire repair shop will do the job with any sealant they have. That IS a system that works. The same with tubes: any “no name” patch on the market will do the job - that is another system that works. But If I have to make research and expensive experiments in order to find which of the many brand sealants on the market can make the job of sealing a small hole (maybe only muc-off can make the job, from so many brand alternatives on the market?), then the system is not reliable.
And, please, don’t shoot me. It is only about my opinion, which was built up on my true experience. There is no issue if your opinion is different.
