Look, the figures are incredibly impressive, especially considering the shortages that the Switch suffered through it's life, but this kind of statistical manipulation is just misleading.
You're comparing a console that is still in it's lifecycle with consoles that have gone through a full lifecycle. Sales tend to taper off in the final years of a console's life so taking an average of one console versus another console full lifecycle is going to skew towards the console that is measured without that tail-end drop-off.
Switch figures are great and considering the lack of price cuts it's doing astonishingly well and is on track to at least make top 3, but save this kind of comparison until you can compare like for like, else it's just misleading.
