tube amplifier auto bias- accurate?


Hi I am new to tubes and this hobby, I read somewhere autobiasing is a gimmick, I was wondering how accurate it is. Is it possible it could be inaccurate? Is there a way to test its accuracy. Also what tube tester is good for beginner.

A question on auto bias. When would an amp perform said biasing? Unless it was a real smart implementation, seemingly auto biasing would be active all the time the amp is on, that is even when music is being played. Wouldn't that have a negative impact on the music?
