I'll be starting my first batch in the incubator next week-please excuse my dumb handturning question. Am I understanding correctly that when hand turning without a carton you mark each side X & O (or similar) and simply flip each egg over each time, doing a perfect 180 always... but in a carton (with the bottom cut out) you are merely leaning it from side to side. alternating propping one end up but not actually flipping it, so not getting a complete 180 degree flip? Forgive me, I like to have it down to a science and am trying to understand exactly what needs to be done.
