Gribble, in the past two years (roughly), there haven't been this many SKUs that have sold notable amounts, and even though there have been multiple SKUs in the chart, it has, by and large, been dominated by one SKU from each console, and as a result, all you've needed to look at was the top SKU. But when you have several bundles charting rather high and rather close, then you have to try and weigh the rankings against eachother. If you don't want to do so, then fine, but I'll continue with my way (which, FYI I haven't changed. As soon as MS introduced several XBO SKUs there was always talk about how the rankings weighed up to eachother).
