Tbh, that solid feeling explains vinyl's comeback.

Yeah the training plan thing is so real. I mean I used to feel guilty for swapping a run for a walk or taking an extra rest day. Now if I feel a weird ache that isn't just normal soreness, I'll take like two or three days off completely. It always feels better to come back fresh than to force it and make a small thing into a big injury.

But how do you decide which slabs get a pass on testing and which ones don't? If a visual check looks good but the concrete is secretly holding moisture, the adhesive failure might not show up for months, long after everyone's been paid. Isn't trusting the data sheets exactly why they list a maximum moisture level for the adhesive to work? Seems like gambling the whole install on a dry-looking surface could cost way more than a two-day delay.

Exactly, like @emma695 said, our whole system gets rigid until it breaks.
