Average of a farm's weekly walk scores. A good walk covers most of the grazing platform, hits around 40 measurements per paddock at 3–5 metres apart, and the recorded heights agree closely with each other. Silage and closed paddocks don't drag the score down.
Farms with few walks are blended with a baseline so a single perfect walk doesn't outrank a farm walking all season. The more weeks you record, the closer your score sits to your real average.
