Fit comparison

Each well's measured viscometer readings scored twice: against the curve regressed from those readings, and against the mud the advisor assumes. R², RMSE, signed bias and per-speed residuals show exactly where the model stops matching your real data. Sweeps come from the Fann lab; the assumed PV/YP is the same one the stage solver uses.

Advisor's assumed mud
The PV / YP dial estimate the advisor falls back on when a well has no measured curve. Editing it here moves the same shared assumption every advisor surface reads.
Per-well fit
Sorted worst advisor fit first. R² is measured against the same readings for both curves, so a negative advisor R² means the assumed mud is worse than quoting the average reading.
