On period started late on 11/23, lasted 11/24, 11/25, 11/26 and 11/27. Slightly higher than normal levels of traffic, but nice hourly conversions. Off period started late on 11/27, persists all day on 11/28 same traffic level (very slightly lower) but absolutely ZERO sales conversions. The clamping is so incredibly obvious!
