Short reads on setup, Hydrogen prompts, and product changes — one useful thing at a time.
Reading your weekly progress report
People stare at weekly reports the way they stare at dashboards — hoping the right number will jump out. Reports work better when you read them looking for one thing.
Monthly patterns vs weekly noise
Last week's "best focus day yet" can quietly disappear from this month's read. Same person, same desk, same job — and a pattern that lasted seven days but not thirty. Weekly reports are loud. Monthly reports are honest. You need both, but you read them differently.
Change attribution: what shifted, not what caused
Change attribution is the section of a weekly report that tells you what likely shifted, ranked by how much your data agrees on the direction. It will not claim causation; it names contributors.
What is in a daily Sarenica report
A daily report is not a smaller weekly report. It is a different artifact — operational, time-specific, and designed to drive one adjustment for tomorrow.
Steps and calories as activity context
Step count and calorie burn are not fitness metrics in a desk-work tracker. They are context for whether your fatigue read is honest, and they show up in the wearable join more than people expect.
Keyboard cadence as a fatigue signal
Typing speed is a weak signal in isolation and a strong one across a session. The drop from minute 5 to minute 35 is what tells you something, not the absolute number.
Mouse idle and the fatigue tells nobody talks about
Most fatigue tracking ignores the mouse entirely. Idle stretches and movement cadence are quieter than camera signals but harder to game, and they line up with the rest of the read.
Sleep, recovery, and next-day focus explained
Sleep hours is the obvious wearable signal and the weakest. Sleep score and recovery are noisier but more honest. How they join to next-day focus, and where the join breaks down.
Posture monitoring: head pose vs back angle for desk work
Back angle is what wearables sell. Head pose is what your camera can actually measure, and it tracks the strain pattern that matters for screen work.
Focus vs concentration: why Sarenica tracks both
Concentration tells you what is happening in the next minute. Focus tells you what happened across the last block. They look the same in the abstract and behave nothing alike in the data.
