Being able to see the first 10 weeks of sales data for each region, for example for Xenoblade Chronicles X, because it released in Japan first, there is no way to see it's first weeks sales for other regions unless you go searching for them elsewhere yourself.
Ah - right, ok!!
This happened because I made a fix to "line up" the first 10 weeks. It used to display the first 10 weeks of each region, but when looking at it in the context of the current output I thought it looked more than a little weird - but yeah, I can see how when a game launches in one region several weeks before it launches anywhere else, you are left with a fairly large data gap...
