Air fuel ratio question

Addicted to finding that perfect tune..I picked up a 4 channel wideband and put them in the right bank and also put a 5th sensor in that collector. The header sensors are all located 10 inches downstream. Made a run and The collector sensor reads 1 unit leaner than the header sensors. Just wondering if that's normal, is that fuel still burning on its way down the header? I wouldn't think fresh air is making its way in the collector at WOT.
