Plateau analyzer — Pro tool overview

Summary

Reads your logged body metrics and dose log to classify the trailing 24-week trajectory against a 0.5%-per-week heuristic.

What this tool does

Reads logged body-metric entries and dose-log entries from your account over the trailing 24 weeks. Fits a deterministic linear regression to the body-metric series. Classifies the slope against a 0.5 percent-per-week heuristic and surfaces the underlying numbers (weekly percent slope, R-squared, weeks at current dose, intercept).

How the heuristic works

Plateau classification uses an absolute threshold: if the regression slope is between -0.5 percent and +0.5 percent of body weight per week over the 24-week window, the trajectory is flagged as plateau-pattern. The classification is descriptive, not prescriptive — the analyzer does not recommend dose escalation. The FDA-label reference for the indicated GLP-1 (re-exported from existing escalation-ladders dataset) is shown alongside.

What the tool will not do

It is descriptive, not prescriptive. It does not output a dosing decision. It does not analyze logged data outside the 24-week window. Compliance allowlists are enforced at the page and sample-preview level via negative substring tests (PLATEAU_BREAKER.md § UI Rules).

Inputs the tool takes

• Existing user-scoped bodyMetrics entries (read-only)
• Existing user-scoped doseLogs entries (read-only)
• Inferred current GLP-1 dose phase (from logged doses)

What the tool returns

• Trailing 24-week body-weight regression
• Weekly percent slope and R-squared
• Plateau / not-plateau classification
• Weeks at current dose, intercept
• FDA-label reference for the indicated GLP-1

Cited literature

• Wegovy (semaglutide 2.4 mg) FDA label
• Zepbound (tirzepatide) FDA label
