Well, baseline is not a scientific term, it is something to gauge momentum and predict the coming weeks. Basically it is: what would the console sell wihtout sales, holidays and new games. But that is obviously problematic, because without these the console would stop selling altogether. Your graph is actually helpful. You see the monstrous Monster Hunter peak for PS4, the Golden week peak for both consoles and some other peaks that probably match with some game release if we would look for it. The other weeks are more 'normal' weeks.

If you look for some way to make a formula which calculates it always the same way, I may suggest the following: You already calculated the average. We can easily say that all above average is extraordinary and created by holidays, sales or game releases. So take the below average weeks and make an average for them. Or even better - replace the average in both cases with the median, if your tool supports it. Median is more stable against a few extreme values (like the Monster Hunter peak). So the median of all weeks below the overall median. But that's just my personal suggestion.

Thanks for the source. He's a pretty trustworthy guy, but I do wish he'd post numbers. From his later conversation where he gave some Ys sales, it looks like we're talking about peanuts though. Happy Switch version had a good FW in West. Hopefully it's well received and it's able to pass up LT sales too.

NISA has brought such an interesting paradigm to niche JRPGs. Almost everything they've brought has done very well on Switch in the West while its JP release completely flops.

Yeah... Its only ahead of PS4 and PSV individually and only launch aligned in the west, of which both the PS4 and PSV versions launched at the exact same time so it would be no surprise that the audience was divided. Its definitely not blowing sales out of the water, but it is a good indicator for falcom on a potential audience. I imagine western sales are still quite poor compared to Japan sales for PS4, so it is unlikely that they... switch their main platform. But in the west Switch might be the bigger audience, if sales hold strong.

Lastly I am pretty sure NIS or NISA would have nothing to do with Ys VIII in Japan. Unless that was just a side comment.

NISA handled the Switch port. Which makes the patch schedule unsurprising.

I am well aware NISA handled publishing in the west, but I said Japan, which Falcom handled on their own.

Now, Nihon Falcom published the title in Japan, but they did not do the port themselves. NIS did - and considering how it turned out, I bet that NIS America handled the Switch port, like the PC port.
