This might be ok for a 10 or 11 speed system, but for an old 5,6,7 speed system then 1% elongation (not “stretch”) is acceptable before it all starts going wonky.

The best thing is to get yourself a precision measuring device like the Rohloff Caliber 2. These are cheap and allow you to accurately measure chain wear in a few seconds without removing the chain. I would also advise changing your chain when the wear reaches 0.075 mm per link (about 0.3 per cent assuming it’s per full link).
This is a lot less than the 1/8 inch for 12 inches (more than 1 per cent) but although it means you will go through more chains you will not need to change the cluster every time you change the chain, things will run a lot smoother and your chain wheel and other parts of the transmission will last a lot longer too.
