How your stats work

Six gauges, three kinds of honesty, and your own normal as the yardstick.

The short version:

Your gauges are scored against your own recent normal — not a population average, not anyone else's targets.
Every stat is labeled by how it's sourced: measured from data, reported by you, or expressive by design. A self-report is never dressed up as a measurement.
Until Eravyr has learned your normal, a gauge says "warming up" — it will not show you an invented number.

1. The six stats — and how honestly each is sourced

Stat	Tier	What's behind the number
Vitality	Measured	Read from your body's signals, against your own normal — or from what you logged, when no device is feeding it. The tile says which.
Strength	Measured	Read from your activity data, against your own normal — or from what you logged, when no device is feeding it. The tile says which.
Calm	Measured	Read from sleep and recovery signals, against your own normal — or from what you logged, when no device is feeding it. The tile says which.
Clarity	Reported	From what you tell us — the focus and creative work you log.
Connection	Reported	From what you tell us — the connection you log and rate.
Spark	Expressive	Playful by design — novelty and chances you choose to log.

You can also create your own custom tiles (Expressive) — name anything you want to track, rate it 1–10 when you feel like it. Custom tiles never pretend to be measurements and never move your measured gauges; they're yours.

1a. What the badge on a Measured tile is telling you

The three Measured gauges — Vitality, Strength, Calm — are read from device signals whenever a device is feeding them. When one isn't, they're moved by what you put in: a quick event, a weekly check-in. That's on purpose. Nobody should open Eravyr on day one, before any watch or ring is connected, and find three dead gauges staring back.

What we won't do is let a tap wear a sensor's clothes. Each Measured tile carries a small badge saying what actually moved it over the last couple of weeks:

Measured — device data fed it.
From what you logged — only your own logging fed it; no device data came in.
Device + what you logged — both did.
Nothing fed it at all? Then the tile stays on its usual warming up / no-reading wording. We don't put a badge on a gauge with nothing behind it.

The badge is per gauge, and it can change from week to week — your Strength can be device-read while your Calm is running on check-ins. Your weekly recap email says the same thing in the same words. Underneath the grid you'll also find the date device data last arrived, so a sync that quietly stops is something you find out from us, not something you discover weeks later.

2. "Your own normal" — what that actually means

For each signal you share (steps, sleep, heart-rate variability, …), Eravyr learns your typical range from your own recent history — roughly the middle band between your personal 25th and 75th percentile over the last ~90 days. A day is then read as below your range, within it, or above it. That's the whole trick: 6,000 steps can be a strong day for one person and a quiet day for another. Eravyr never grades you on someone else's thresholds.

3. Chapters — because life doesn't hold still

Started a new medication? New job? Training block? Recovery stretch? Declare a new chapter. Eravyr re-learns your normal for that chapter, easing over from your established baseline while the new one warms up — so a real life change isn't scored as if nothing happened. Your history keeps the old chapters; the gauges track the one you're in.

4. Warming up — no fake numbers, ever

Until a signal has enough of your own readings (about ten) to know your range, its gauge reads "warming up" instead of a number. Reported tiles read "tap to rate" until you've actually rated something. And while your baselines are warming, Eravyr sends no nudges at all — it won't alert you off numbers it doesn't trust yet.

5. Drift toward neutral — why an idle gauge settles at 50

Each gauge drifts gently toward a neutral 50 when nothing new comes in. That's deliberate: your sheet reflects your recent past, not a trophy of your best-ever month. Show up again and it moves again.

6. Level — earned by showing up, not by volume

Your Level grows with the number of distinct days you've shown up — logged something, checked in, shared data. It follows a square-root curve, so early levels come quickly and later ones take real consistency. Logging twenty things in one day counts the same as one: a single active day. There's no way to buy it and no way to binge it.

7. Nudges — suggestions, never alarms

When a measured gauge sits low or dips, Eravyr may queue a gentle suggestion — "Your Calm has been on the quieter side lately — time outdoors in daylight tends to help." No scores, no digits, no sirens, and you can dismiss it. Eravyr is a reflection tool in the general-wellness lane: it does not diagnose, treat, or replace your clinician.

8. The honesty rules this page is bound by

A measured number always comes from data; a reported number is always labeled as yours.
A Measured gauge that was moved by your own logging says so on the tile and in the recap email. The tier describes how a gauge is designed; the badge describes what actually fed it.
An estimated or seeded value, if we ever show one, is labeled "estimated" — and is displaced the moment your real baseline exists.
If we can't compute something honestly yet, the tile says so instead of guessing.
This page changes when the code changes — not before, not after.
