I don't know man, my link seems more realistic it was only February where it started beating switch, and after the discounted xbox it started beating switch as well, and it came out be true for NPD.

It is not really a matter of opinion in this case, as the link you provided includes a variable that is irrelevant (top rating). The link I have only looks at whether the item has the terms "console" in its title or description and then sorts it by best selling. The data for your link and my link are the same (they are both from Best Buy US) it is just that yours not only sorts by sales but also by ratings, which means that the rank you are getting is based on both unit sales and customer rating (obviously the customer ratings is not what we are interested in, so including it introduces error); mine only does it based on unit sales on products that have console in the name or description (considering we are only looking at console sales, the way my link has sorted the data gets closer to what we are looking for than your link which includes customer ratings).
Also, I should note that the link I provided had PS4 above Switch during black Friday week in November (I don't recall Xbox One), then Switch above PS4 and Xbox One in December, PS4 above Switch starting in late-January and the Xbox One started to beat the Switch after the discount (and on the first day of the discount one the Xbox One SKUs was above the PS4 but it went back down again), after the discounts ended Switch went back above Xbox One and starting on the second week of March it went above PS4. So this sorting seems to be receptive to changes in sales patterns and only changes in sales patterns (as opposed to changes in customer rating patterns).
