Per best practice pog should be scanning stand alone research after they're done setting, filling, and backstocking. If something has multiple salesfloor locations they need to spread out what is on the floor, or key what they see if it is less than enough to fill all facings for both locations. If your scans with location score is blowing up after new sets, something is wrong with either your PTM process or capacities are off for another reason. Using EXFs will help keep your score green after pog sets an aisle, but that EXF will usually create replenishment problems down the road. Basically either take the hit now and work on the issue, but have an accurate accumulator, or run with an off accumulator and take the hit later while experiencing replenishment issues until it is fixed.
