Should You Play Ranked Today? Five Signals That Say Queue — or Don’t

You ready-check every game but never ready-check yourself. Five evidence-backed signals — sleep, reaction drift, lapses, restraint, mood — that separate climb days from donation days.

Every League player knows the donation day: you queue anyway, play three, lose three, and end the night wondering why you did that to your LP. The information to skip it usually existed before the first queue. You just didn’t check it.

The five signals

• 1. Last night’s sleep. The heaviest, most boring signal. One fully skipped night slows simple reactions ~49 ms and multiplies attention lapses ~5× in lab conditions; even a few short nights stack a similar debt. If sleep was bad, every other signal below is probably bad too.
• 2. Reaction drift. Not “is my reaction time good” — is it at your normal? A practiced player sitting +30–50 ms over their own baseline is functionally playing on someone else’s hands.
• 3. Lapses. Moments where the light flared and you just… didn’t respond for half a second. Lapses are the signature of fatigue and they map straight onto “the gank was on your screen and you didn’t react.”
• 4. Restraint. Can you NOT press? Impulse-control wobble is the earliest tell for tilt — errors of commission show up before you feel tilted (and being frustrated makes you worse at noticing).
• 5. Self-reported state. Three sliders — sleep, energy, stress — answered honestly. Self-report is imperfect, which is why it’s one weighted signal among five and not the whole verdict.

Baselines or it didn’t happen

Each signal only means something against your history. That’s the entire architecture of our daily check: five weighted slots (vigilance 30%, reaction 25%, tracking 20%, flexibility 15%, state 10%), ~3 minutes, compared to your rolling 14-day baseline. Under three sessions of history, it refuses to score you at all — a readiness number built on two data points would be astrology with extra steps.

What the verdict can and can’t say

A low score doesn’t mean you’ll lose and a 100 doesn’t mean you’ll win. What it says is that your measurable capacity — speed, attention, restraint — is or isn’t where it normally lives. After enough paired days, we show you the honest correlation between your readiness and your own results, whatever it turns out to be. Some players’ outcomes track their state tightly; some don’t. Yours is an empirical question, and it takes about two weeks of data to answer.

Honesty note: readiness is a probabilistic personal signal, not a win predictor — and training sharpens the skills you drill, which your ladders measure. Nothing here promises LP.
