The idea is to have no fixed deadline nor specific time that the graph refreshes for the new day. Rather, the graph is refreshed continuously and the flatlining happens second-by-second. So the countdown to derailment is always a function of the exact amount of work you’ve done so far. If you’re about to derail, do a bit of work and bump your datapoint up a bit. If you do a tiny bit of work you might bump up your datapoint enough to give you another hour of safety buffer. If you want to go to sleep, do enough to give yourself at least 8 hours of safety buffer. If you do the full daily rate you’ll buy yourself another 24 hours of safety buffer. The deadline is always whatever you want it to be without any UI. The entirety of the interface is: do stuff that makes your datapoint move, graph tells you how much time you have before you have to do more.
There is more philosophy on the linked page, but that’s the quick summary of continuous beemiding.
