Famitsu numbers has Switch up 300k this year compared to last, while this comparison has it at only 25k. Are VGC numbers that much off (they're usually quite similar to Famitsu) or have you put in the wrong number somewhere? |
Different weeks counted.
Famitsu ends on Sundays for a start, VGC weeks end on Saturday (though this doesn't make a big difference except when those days cross specific holidays)
Famitsu figures are also more recent, the latest week is for w/e Sunday May 16th, VGC latest week is for Saturday May 8th
Main thing though is that for VGC week 1 of 2021 is w/e Sat 9th Jan, whereas for Famitsu week 1 of 2021 is w/e Sun 3rd Jan.
----------
So these are the actual date ranges being compared:
Famitsu:
20 week ending May 17th 2020 vs. 20 weeks ending May 16th 2021
VGC figures PAOerfulone is using:
18 weeks ending May 2nd 2020 vs. 18 weeks ending May 8th 2021
----------
This means VGC figures for 2020 include the week that crosses the New Year, which is a big sales period in Japan, wheras the figures for 2021 don't include that week. I do think it's a mistake when doing direct weekly comparisons, but that week would have to be put somewhere for yearly comparisons.
