I think that's still a valuable log entry. You should be able to look back at your log and see the periods of inactivity, possibly being able to identify or correlate the time associated with other life events. Maybe you can work on finding ways to identify and exit those periods sooner.

I believe everyone has times of marginal productivity in their lives, maybe some more than others. But if you can average out ahead of the curve, what does it matter? Showing the fact that you've had a slow week but finished the month on a high note seems like a great capability.

And if an employer doesn't recognize this and can't measure your net output, then hopefully another employer can.
