Observed - MM reference (kt)
Always on the VPP grid, regardless of the Grid setting above · positive = beat the polar at that cell · negative = underperformed it · "na" = one side has no data (observed cell dropped, or this target has no solution there)

Grid uses the observed data's own resolution — 5° TWA bins, the same 7 TWS bands as the Polars page — not the VPP tables' exact grid points. Switch to "VPP grid" above for a row-for-row comparison against WCE/WCN/MM. Cells need ≥5 raw readings to show (same threshold as the Polars page).

The "Observed − MM reference" diff table below (and in the PDF download) is always on the VPP grid regardless of the Grid setting above — pick which target it diffs against with "Diff vs."
