Depth errors, rain-area percentages and volume errors compare the same valid footprint. A partial coverage percentage means part of the region is unverified. For windows awaiting verification, amount and rain-area columns show each source’s known area; errors remain blank. Missing rain remains unavailable; dry zero remains valid.
