Looks like the calibration and test only takes around 5 seconds. No wonder the calibration isn't that accurate.

The assembly line (baofeng) looks like 2 places where the radio is calibrated, meaning they spend twice as time on calibration as one of the steps in the chain.

OK.

The radios are still not calibrated correctly even if they take 2 x 5 seconds.

yes i agree with you
I see that the work is very manual, and the tests are scarce.
Just watch if it works and enough.
I think they do more tests on the toy retevis than on the double band baofeng.
