imp.bidfloor is a CPM floor — per impression, not per play. imp.qty.multiplier 1 scales impressions per play: per-play cost = (CPM/1000) × multiplier 2. Multiplier already shifts with daypart and venue — floor rules keyed on those axes risk overshooting the effective per-play minimum. Bid flow: 27.

- Round multiplier 1.3 to 1.0 and lose 23% of per-play revenue
- PBS enforces floors CPM-vs-CPM; multiplier only affects billing
