I wax my board often and I do notice a difference from when I slack for a while. Though it should be noted that I ride midwest fake snow/ice pellets. I also run 400 grit sandpaper over my base every few times I wax to structure it. That could be making the difference alone.
Eh go for it I'll continue to state the truth and refer to it as psychological what the difference is.
I think you've stumbled into a good topic for one of your tech articles. Set up a blind test with identical set ups. Both structured as you like. One waxed and one not. Might take a little doing but it will certainly be interesting.
