Yes you are 100 percent correct that you must keep the chain in the hox wax long enough to heat the chain so the wax adheres to the metal and melts the old wax away completely. I thought I was clear to say 10 seconds for each draped section was enough time for this to occur. In my opinion, 10 seconds or 1 hour won't make a bit of difference. But any less than 10 full seconds in hot wax won't be long enough to heat the chain's metal enough--you should see a shiny clean chain exiting the pot as you rotate it through.

I use Dura Ace chains with Shimano break off pins--I still don't like the idea of master links from what I read online (obviously Shimano doesn't either so I'm not alone). I also don't see any advantage to breaking and re- installing a freshly waxed chain. Much easier to just rotate it through using my drape method imo. Fishing a waxed chain out of a pot and fiddling with a long dripping snake and then installing it while it flakes fresh wax all over seems like senseless hassle. Why not just leave the chain installed and rotate it through? Seems like a no-brainer to me but hey, whatever you like.
