In between sets!? I've found that if I do any activity in between sets (like watching Twitter) I'll just end up spending way too much and then make the exercise session super long. Also I can't focus and write a serious prompt or review serious results in just or 3 minutes. But maybe it works if the app is sonething you've recently worked on and you already have very clearly in your mind what you want, it just needs to be done.

For incremental changes 1-2 sentences are usually enough. Also, since the program itself is a workout app with live reload, I can actually fix bugs while I’m using it.

As for too long of a wait I agree, it makes the sessions longer. Ideal window is after a heavy superset where waiting for 3-5 minutes is not a waste.

(Note that I’m not doing this for my real job, just for my personal project)
