Each chart tracks up to six behaviours (paths), each with its own name, colour, and symbol. Paths with no data are hidden automatically.

Sum adds all counts and observation time; First / Middle / Last pick one session by position; Highest / Lowest pick by frequency.

Celerity automatically detects trend lines from 7 or more consecutive data points moving consistently in the same direction. These appear in the Auto-detected section of the Trends tab. They cannot be deleted but their chart visibility can be toggled with the eye icon.

• Trend — the fitted celeration value. ×1.25/wk means frequency multiplies by 1.25 each week. Acceleration paths show ×, deceleration paths show ÷. A significance label (e.g. Acceptable growth, Robust growth) appears for acceleration paths.
• Bounce — total width of the bounce envelope (see section 7).
• Med — median frequency of data points within the trend range.

• Log-residuals are computed for each data point: actual log₁₀(freq) minus predicted log₁₀(freq).
• The standard deviation of those residuals is computed.
• The envelope edge is placed at ±2 SD from the trend line on the log scale.
• At ±2 SD, approximately 95% of data from a normal distribution falls inside the envelope.

Points outside the envelope are considered statistical outliers. The further outside the envelope a point falls, the rarer it is. Distances are expressed in course widths (CW) — the full envelope width from edge to edge.

The bounce value (×N) displayed in the stat box and hover tooltip is accompanied by a smoothness rating:

• Click Setup → Aims tab, or click the standalone Aims modal button. Choose a path, direction (Acceleration or Deceleration), target frequency, and target date. Click + Add Aim Star.
• Enable Min trend line to draw a dashed minimum-slope line from the start date to the aim star — showing the minimum rate of change needed to reach the target.
• Drag the star to reposition it when the chart is unlocked.
• Aim Stars also power Learning Picture detection — the Aim picture requires aim stars to be set and performance to be at or near the aim level.

A shaded horizontal strip between an upper and lower frequency — useful for showing a performance criterion range. Set Upper, Lower, optional start/end dates, and a colour. Click the eye icon to show/hide on the chart. Manage bands from Setup → Aims or the Aims modal.

• Add manual trend lines, view auto-detected trend lines, and manage Improvement Index (I.I.) pairings.
• The eye icon on each trend line controls on-chart visibility only — it does not affect whether the line feeds into the other tabs.
• + Add I.I. Pairing — pairs one acceleration path and one deceleration path to compute an overall accuracy index. The I.I. stat box appears on the chart.

Compares consecutive trend line periods, showing how rate of change, frequency level, and variability shifted between phases. Each comparison generates a stat box on the chart.

• Celeration turn — did the rate of change speed up or slow down?
• Frequency jump — did the level shift up or down at the phase boundary?
• Level change — the ratio of median frequencies between phases.
• Bounce change — did variability increase or decrease?
• I.I. Change (I.I.C.) — how did overall accuracy shift between phases?

Eye icons control on-chart visibility of each comparison's stat box only — they do not affect the Summary Table.

Detects 7-point runs — seven or more consecutive data points all moving in the same direction. These are statistically significant trends that may indicate a real change in performance. Runs are listed by path with date range and direction.

A structured table of all stats across all trend line periods — trend values, bounce, median frequency, I.I., phase comparisons, and more.

• Use the eye icons to show/hide individual periods on the on-chart overlay.
• Export as SVG (best for print), PNG (screen image), or CSV (spreadsheet data).

Shown when the cursor is within ~12 SVG pixels of a data point. Displays:

• Path name (in the path colour)
• Date, count, and time observed
• For outliers: distance beyond the bounce envelope in course widths, and the associated probability

Shown when the cursor is within the bounce envelope band. Displays:

• Path name (in the path colour)
• Trend value with Acceleration or Deceleration label, and significance label (acceleration paths only)
• Bounce value and smoothness rating

Data point tooltips take priority when the cursor is near a point.

• The aim has been met in 2 of the last 3 sessions — consider moving to the next step.

• Performance has decreased in each of the last 4 or more sessions in a row
• Performance has increased in each of the last 4 or more sessions in a row (for deceleration paths)
• Performance has stayed flat across 4 or more consecutive sessions
• Acceleration rate below minimum (×1.25) — current rate shown
• Deceleration rate below minimum (÷1.25) — current rate shown
• Performance has fallen below the trend line in each of the last 3 sessions

When a Learning Picture is detected and the Decision Support panel is open, thick solid trend line highlights draw on the chart for each paired path — covering the most recent trend period plus one period forward. Use the eye icon next to each picture name to show or hide its highlight.

Completed guides are listed in the Decision Guide modal under their tree (Skill Acquisition or Generalization), sorted newest first. Each row shows the date, recommendation, and chart type. Click View to review the full Q&A path in read-only mode.

• Measure daily. The SCC is designed for daily data. Gaps reduce the reliability of celeration estimates.
• Keep observations consistent. Use the same duration each day when possible.
• Use fair pairs. Track both the target behaviour and an incompatible alternative.
• Use clear pinpoints. "Reads words correctly" is better than "engages with text".
• Start a new cel line at each phase change.
• If frequency is not moving, change something. A flat celeration after 3–5 data points is a signal to adjust.

• Use Daily/min as your primary chart. The traditional SCC runs Mon–Sun for 20 weeks.
• Celeration targets: ×1.25 to ×2.0/wk is common for skill-building. Above ×2.0/wk is a steep learning rate.
• Bounce benchmarks: Below ×2 is tight. ×2–4 is typical. Above ×6 suggests the programme needs attention.
• Prefer Theil-Sen. PT data frequently includes atypical days.
• Read the chart first before checking the stats box.
• Export as SVG for reports.

• Open the Decision panel regularly. It checks all paths for advance and review criteria automatically.
• Pair your paths. Link acceleration and deceleration paths in Setup → Data Paths to enable Learning Picture detection.
• Name the picture. Identifying the current Learning Picture (Crossover, Jaws, Dive, etc.) helps communicate progress to teams and families.
• Use the Decision Guide. When a review flag appears, run the guided decision tree — it uses your chart data to auto-suggest answers and produces a saved recommendation.

• Click 💬 Help in the top bar. A panel opens in the bottom-right corner of the screen.
• The panel shows suggestion chips — topic categories to help you get started quickly.
• You can also type any question directly in the input field and press Enter or click Send.

Each category shows a ← Back chip to return to the top level. Chips disappear once you send any message. Click ↺ Clear to reset the conversation and restore the chips.

The Help AI does not read your chart values automatically — you share them, and it interprets them. To get an interpretation:

Even without reading stat values, the Help AI receives context when a chart is open:

• Chart type — used to convert celeration periods into real time (e.g. each period = 1 week on a Daily chart)
• Data path names and roles — used to tailor language to your domain
• Pinpoint — the behaviour description from Setup
• Data domain — set in Setup → Data Paths; enables domain-adaptive language for Learning Pictures and interpretation
• Detected Learning Picture — when the Decision panel is open, the AI knows which pattern was detected

• Each Help AI conversation is limited to 10 exchanges — shown as a counter in the panel header (e.g. 3/10 exchanges).
• When the limit is reached, click ↺ Clear to start a fresh conversation.
