The quarterly numbers are the biggest help for adjustments as we generally know how the usual gap between shipped vs sold. Though, right now that gap is far smaller than usual due to the shortages. Even Switch stock is more limited than what is typical.
One way I use historical data is looking at how much above or below PS5 and Xbox Series X|S sales are compared to PS4 and Xbox One. And for Switch how well sales have been compared to last year, 2 years ago, etc. Of course I also use all available data.
Not to mention Sony mentioning their own estimates of sell-through when there is a milestone or how close it is compared to PS4. I would say that for any given month VGC could be even 25% off (not normal), but when looking for LTD it would be less than 5% off.
That slipped my mind. You are correct. When we put PS5 estimates at 10 million we were exactly one week ahead of Sony's own sell-through estimates my one week. While we were close I did adjust our estimates to match Sony's.
