My only disagreement with this is that there are some things that result in a more efficient unload. For example, as you put utensils in, grouping like utensils will result in a more efficient unloading. It's sort of like insertion sort, you start wit an empty set, insert a fork in one area, next you insert a spoon where spoons go, etc. It is marginally more effort than placing them in.

I do agree though if you load you get to load however you see fit. So carry on with doing stuff!
