12 years of logging data and the answer is give or take what you said. Every hour past 7pm is exponentially worse productivity wise (aka 7 to 8 vs 9 to 10 vs 12 to 1 is night and day). There’s also a catch up factor above which subsequent periods are impaired.
Basically if @20/30 hours per week it’s 70% ish productive at 60+ it’s max 50% which tells you a ton about the marginal productivity of those incremental hours.
There’s also time of week variation, time of day variation, the aforementioned burnout recovery spillover occasionally and a bit of sequencing at play.
- Fawlty 6y agoThat's an impressive time series and some pretty interesting results. How do you log that? How do you measure productivity?
- texasbigdata 6y agoRescue time, tag at the application level (obviously not fantastically accurate), and sub tag in chrome based on website. It’s directionally correct at best, but still helpful. Would also do a secondary form of manual evaluation by paying someone to text or call with a daily list of questions, but only have about 1.5 of years of data there. I ran the regressions and they are highly correlated in a time lagged way. In particular, sleep, for me, drove a lot of everything else. But from there it’s hard to say what the causality is (were you tired because of work to begin with? Or were you unproductive because of sleep?)
- leoedin 6y agoWould you say you're most alert in the morning or the evening? I've always found myself alert and energised in the evening, and sluggish and unalert for the first few hours after waking. I'd be very surprised if my productivity drops exponentially in the evening. My partner on the other hand is most alert in the morning and loathes doing anything complicated after dinner.
- texasbigdata 6y agoProbably varies by person. Also blood glucose and overall cortisol seems to matter. And if burnout is at play then that’s a meta aspect as well.
