The minutes an interruption takes are not what it costs. What it costs is the climb back into focus, charged again from the bottom. How big that climb is, nobody has really measured; for some work it’s nothing at all. Which is why a calendar cut into hours is not the same calendar.
What it says
A five-minute interruption never costs five minutes.
Getting into deep focus is the expensive part.
Once we’re in, staying there is nearly free.
So an interruption charges us that entry price again.
And then we notice nobody can say how big that price really is.
For easy work, getting back in costs almost nothing.
