I tracked my WFH vs office productivity for 6 months — herE's the actual data

I wanted to settle the debate for myself with actual numbers, not feelings. Tracked output across 6 months: 3 WFH-majority and 3 office-majority (before and after my company's hybrid policy changed).

What I tracked: Deliverables completed on time, deep work blocks per week (90+ min uninterrupted), and subjective energy at end of day.

Results:
- On-time deliverables: 94% WFH vs 87% office
- Deep work blocks: 4.2/week WFH vs 2.1/week office
- End-of-day energy: significantly higher on WFH days (7.1/10 vs 5.3/10 average)

Confounders: Commute fatigue, my specific role (deep technical work), personal discipline. This data doesn't generalise, a role that requires lots of collaboration or mentoring might skew the other way.

But for my specific role? The data strongly supports WFH for productivity. I've shared it with my manager as part of my hybrid arrangement.
