So now results are in, seems this is the first month this tool got the positioning wrong. Seems the end of year is definitely going to be difficult to predict in this way, however it did perform admirably for the summer months. Used ratios from tool against NPD sales numbers to make the bottom table, which makes it easier to understand how undertracked/overtracked each system was imo.
