Some brands, like Campy, can show little elongation, when measured properly, pin to pin over a 12" length, or full length, but still exhibit extreme roller and side clearance wear. I used a Campy 10 chain for 6,000 miles and it showed far less than 0.5% elongation. A new chain skipped on two of the most used sprockets after only 6,000 miles on the cassette. The new SRAM AXS 12 speed chain may do the same thing. Some people are reporting little wear after 6,000 miles. That's impossible.
All cassettes and chain rings eventually wear out. If you repeatedly switch from a worn chain to a new one, eventually you'll get new-chain skip on the cassette or chain suck on the chain rings. If you had a chain with only a few hundred miles on it, it wouldn't skip on the most worn sprockets.
