Analytics and AI reports

Analytics turn an athlete's history into guidance: are they ready or fatigued? What happens if I increase the load? Who should I look at today? These are estimates for information only, not medical advice.

Load numbers in a nutshell

NumberWhat it means
Fitness (CTL)underlying condition: average load over roughly the last 6 weeks. Rises and falls slowly.
Fatigue (ATL)recent tiredness: average over the last week. Reacts quickly.
Form (TSB)fitness minus fatigue. Positive: fresh. Strongly negative: accumulated fatigue.
ACWRlast week's load divided by the average of the last 4. Between 0.8 and 1.3 the load is building gradually; above 1.5 it is rising too fast.

Each session's load is computed from heart rate; without it, from pace; without that either, from duration. For reliable numbers set max HR and resting HR in Athlete settings.

Readiness

Athlete → Readiness (the page is titled "Load, form & records"). At the top is the verdict: Ready (green), Caution (yellow) or Fatigued (red). Pick the Method with three buttons; those without data are greyed out.

MethodHow it decides
HRVcompares today's heart-rate variability with the personal average of the previous 7 days. It needs 7 measurements in 7 days: until then you see "Baseline: n/7 days".
Load (cardio + strength) / Load (cardio only)uses Form: −10 and above Ready, between −10 and −20 Caution, below −20 Fatigued.

Below you will find the fitness, fatigue and form chart, VO2max estimated from runs, and records: best time over 1 km, 1 mile, 5 km and 10 km, and the longest workout by time and by distance.

Digital Twin: simulating a plan

The Digital Twin projects the athlete's condition forward and answers two questions: "where will they be in a few weeks if they carry on like this?" and "is the change I have in mind risky?". It uses the same models as the Readiness page; it is not artificial intelligence and it does not predict injuries.

  1. Open the athlete → Digital Twin.
  2. At the top check Data reliability (High, Medium or Low) and the reason. High reliability needs at least 8 weeks of history, 2 sessions a week and a recent last session. Check calibration shows how far off the twin usually is for this athlete.
  3. Choose the Horizon, from 2 to 12 weeks.
  4. In the Levers tab move volume, intensity, sessions per week, deload week or initial break. Or, in the Plan tab, pick one of the athlete's plans and how many times a week to do it.
  5. In the charts compare the coloured line (Scenario) with the grey one (If nothing changes). What matters is the gap between them.
  6. Go through the Risk indicators week by week: green no signal, yellow keep an eye on it, red attention.

The Proposal tab builds a week-by-week load plan by itself. It suggests a Phase (Build, Maintain, Deload, Return) with an explanation and sticks to cautious limits: at most +10% a week, a deload every 4 weeks (every 3 from age 50), ACWR no higher than 1.3. You can correct the loads in the table by hand.

The "monotony" and "strain" indicators show up almost always in simulated scenarios, because all simulated sessions in a week are identical: they are not a real alarm. The other signs are.

Time machine: restarts the twin from 30, 60 or 90 days ago and compares its forecast with what actually happened. It helps you judge how far to trust it.

Think Center: every athlete at a glance

Menu Think Center. It works without AI too: it shows how many athletes need attention, are inactive or on track, and one row per athlete with a coloured dot.

DotWhen
Redinactive for more than 7 days, or readiness "Fatigued", or ACWR above 1.5
Amberreadiness "Caution", or ACWR outside 0.8–1.3, or last session more than 3 days ago
Greeneverything else

Filter by colour and sort by last activity, readiness, 7-day load or name. Click an athlete to open the report panel.

Setting up AI for reports (Ollama)

Written reports are produced by a language model you host, with Ollama, on the same PC or on a computer on your network. cronowiz Studio ships no model and uses no external service. It is optional: everything else works without it.

  1. Install Ollama from ollama.com and download a model from a terminal, for example ollama pull llama3.1. Bigger models write better but need more memory.
  2. In cronowiz Studio open Settings → Virtual PT (LLM · Ollama) and turn on Enable.
  3. In Base URL keep http://localhost:11434 if Ollama runs on the same PC; otherwise enter the address of the computer hosting it, for example http://192.168.1.50:11434.
  4. Press Test connection: you should see "Connected". The API key is only needed if Ollama sits behind a proxy that requires one.
  5. Choose the Model from the list and press Save: without Save the settings are not kept.
When you generate a report, the athlete's summary numbers and name are sent to the Ollama server you set. GPS tracks, beat-to-beat intervals and videos never leave the computer. With Ollama on the same PC nothing leaves at all.

Generating a report

  1. In Think Center click an athlete.
  2. Choose the Report type: Period summary, Readiness & load, Performance progression, Next session, Load progression (explains the Digital Twin proposal) or Full report, which combines them all.
  3. Choose the Window in days (28 by default) and press Generate. The text appears as it is written, in the program's language.
  • At least 2 sessions are needed in the chosen window; otherwise widen it.
  • Every report is saved. If new data arrives in the meantime a notice appears: press Regenerate; the previous version goes to the Archive.
  • Copy puts the text on the clipboard; Export saves it as Markdown or PDF.

Didn't find the answer?

Write to info@ypt.ai: tell us the cronowiz Studio version (at the top of the window, for example "v1.0.0"), your operating system and the exact text of the message you see. A screenshot always helps.

This manual covers cronowiz Studio version 1.0.
