I have also found that tuning from the bridge gives the most accurate tuning, although, attaching to the sound hole or neck head seems to work pretty darned good as well

It works as well as most/all of the clip-on tuners you see on various guitars and ukuleles nowadays, but if you have one of the chromatic tuners that don't directly clip on (like the Intelli IMT series), then this will make it work 100x better (okay, slightly exaggerated) because the ambient noise is not picked up by the tuner's microphone
