@smallerstick so if it checked or damaged they would just rip it up and nail another piece down?
Checking doesn’t matter. If a block (or more) is worn, they are simply pried out and replaced. No nails, just a press fit. Repair of end grain floor is about the easiest “fix” you could imagine.
BE the change you want to see.
