When they’ve gotten good at taking (admittedly arbitrary) intentions to return to a task seriously, and can spend a couple of hours on a hard thing knowing they can trust themselves to spend another couple hours if that’s what it takes to master it.
I think that right there is the core benefit of a several hour committed work block. Having a level of moment to moment commitment that makes it so you don’t just stop when things get hard. The other things you mention are also useful tips, but they aren’t inherently baked into the practice you suggested (through any sort of checklist or workflow).
I don’t want to bake the intended lesson into the practice; if I have to tell you what the moral of a story is then it’s not doing a very good job of making its own point.
