I've done the cancellation line for a number of popular shows and every time I've gotten in line several hours before the box office opens. I can't say for sure what the Hamilton line is like on Broadway but at the public people were there at 9 or 10. That was pretty consistent with my experience with other popular shows as well.
I would imagine the procedure on Broadway would be standard where they start selling to the cancellation line when the box office opens if tickets are available. If not, you can wait because tickets may open up during the day. When I went to the show a few weeks ago there were people still standing in the cancellation line when we entered the theater. (Never give up hope!)
(That also tells me the procedure is not exactly the same as at the public, where they took your name and you came back to find out if you got tickets. Tickets were given out in order. This looks like it's done the more traditional way.)
I like cancellation lines. It's fun to meet other theater obsessed people. :) Not sure I'd wait from morning until curtain for an evening show though!
