i think what ever makes you happy is the best way

i personally do this for pleasure more than anything. i have to also hand turn them so they end up being touched a lot. we candled ours on day 6 just because I'm new at this too and its too exciting to see whats going on in there. i bet after i do it 10 times ill be doing it "the right way" but I'm learning and having fun. there were a few that didnt look good so we marked them and checked them again on day 10. ill probably end up candling them a couple more times. I'm sure its better for the eggs the less you mess with them but then again i don't have high expectations and i just want to enjoy the process. wash your hands, be gentle but don't take too long and just enjoy. thats my philosophy on handling my eggs.
