Good video and nice cook. I myself cook wings on HIGH setting cause Kimmie wants crispy skin on her wings.
As for times, that's about normal for the most part so you did real good. Love using mine in the winter because the cold really does not effect the cooking ability of the SRG. Now TBE can be another story because there is not solid lid, but that's for another time.
Just remember to stay at lease 3 in's off the bottom of the basket (using half racks) and you will be good for 99% of you cooks
As for the smoker box there are mods for it if it does not work well for you.
