weighted_avg_velocity was a naive mean despite the name — a 500-flat ЖК weighed the same as a 20-flat one. Now count-weighted by flats_total (sql.md AVG principle): Σ(velocity*flats_total)/Σ(flats_total). Competitors with unknown flats_total are excluded from weights; if sizes are unknown for ALL, graceful fallback to the simple mean (den>0 guard). Field name + API contract UNCHANGED (zero consumer ripple — traced: only CompetitorsSummary, no frontend ref). Tests: equal sizes → weighted==naive (existing 6.0 stays); NEW test with 500-flat@40 + 20-flat@2 → 38.54 (not naive 21.0), proving the weighting. |
