I find this incredibly useful. I work on a relatively small tech team as a lead/project manager/manager and every so often I get very busy where I only have 1-2 hours a day to do my dev work. I've also seen other devs and sysadmins collapse under a work load where they were in meetings all day every day. It can be very tough to get a schedule set where you're able to work on your top priorities, so I value these stories and techniques.
