With enough practice and experience, you can get a feel for right tension when pushing on chain. Until you get that feel down, chain should be checked regularly and tension inspected. Only adjust if necessary.
Hard to quantify, what you need is CCT with gauge. Some kind of calibrated mechanism to keep chain at proper tension.

That is why the factories designed Automatic Cam Chain Tensioners way back in the Late 1970's/Early 80's.
Most of them are quite reliable with standard tension valve springs & standard lift cams.
