So for a lot of Switch software you're basically waiting for official sold through numbers as a reference point to adjust tracking?
I initially came here to see if you were planning on adjusting any Switch numbers since Splatoon 2 seems very undertracked, but (after reading OP and) seeing the mammoth project you have on hand here I can only give cudos to you.
Thanks for your hard work!
The problem is that doesn't help me identify which specific countries/regions are undertracked, so while we can be pretty sure xxxxx game is undertracked overall, the question I then need to ask in order to make an adjustment is in which countries or regions and by how much? I can't just add phantom numbers to the overall to make up the numbers, I need some solid evidence of where I should be increasing the figures, and that will then filter into the overall figure.
Taking the specific example of Splatoon 2 however, I haven't gotten to it in my list of titles to adjust in the US yet, so there may be an increase pending there. In terms of Japan we're slightly over compared to MC and Famitsu but within the margin of error; the UK and Germany is spot on; and France is maybe a touch under, though I'll obviously need to wait until all of our figures are up for 2017 before I can check against the recently revealed figures there. The rest of Europe is also slightly under and will be adjusted up if/when I make changes in France.
That covers the major markets but as you can see it won't really amount to a huge increase. Unfortunately we don't do any tracking in the RoW, and data is hard to find for it, so either the game has a surprisingly high digital attach rate or Switch is doing better than expect in the RoW, in which case the solution is an adjustment to our extrapolation for it, but like I said in the previous post I need some evidence for that before I'd be able to make a successful case for changing the calculations to Brett.
@Poweranimals - Keep in mind the Nintendo figures include digital. But yes, some of them are undertracked (and iirc from when I last checked, one or two are also overtracked). They'll be adjusted as and when I get to them, while I'm going through each region making changes.
