Late response, but I think the best way is to invest your time into figuring out the best settings for you. That's really the best way with these dynamic settings I've provided. And every shop is different since some are more popular/filled with ABers than others.
Try increasing from 2 - 4 to 4 - 6? Add 2 seconds to the stocked/unstocked refresh times.... maybe for one of the pair... until you find something that works well for you.
I have seen some people run something like:
4-7 stocked
5-12 unstocked
