Retail corridors rarely behave like airports — shoppers pivot sideways, carts snag on promo wings, and shelf-edge LEDs compete with handheld glare. We lean on paired observation blocks: one camera log from shoulder height, another from cart basket sightlines.
Those paired logs expose conflict zones where shelf animations repeat faster than shoppers can finish reading pricing strips. When that happens, we lengthen cadence on alternate shelves rather than dimming brightness wholesale.
Finally, we archive paired logs alongside technician sheets so future rotations inherit honest dwell numbers instead of theoretical averages imported from older pilots.
