How readily and near-estimate this market clears — sell-through, estimate reliability, and depth, blended into one score. "Meets estimate" is the share of sold lots hammering at or above the low estimate, over catalogs that print a real appraisal: a house whose printed low is a starting bid would meet its estimate on every lot, so those lots are excluded from this term only — their prices and outcomes still count in the other two.
