What do you argue then? That Nintendo's PR is bad at math, but they should be blindly trusted anyway?

April 2017 covered April 2nd through April 29th. Mario Kart 8 Deluxe released on April 28th.

That makes 165k Switch consoles sold in only two days (82.5k per day) while the preceding 26 days averaged ~4.4k per day.

OR...the whole damn 7.38 million extrapolated NPD figure is wrong.

You guys keep talking about the possibility that Nintendo is wrong while simultaneously accepting an extrapolated figure as gospel.

Nintendo has released precise numbers for the Switch before the NPD Group did and within a margin of error of <100k ... 

There's no viable reason to believe that Nintendo doesn't have precise data especially when they practice telemetry so they can immediately receive data if a new Switch unit was activated or not through each unit's unique hardware ID which automatically translates to sell through numbers ... (9/10 households have internet access in the US so the method I proposed is fine for collecting high quality data) 

And Nintendo did give us hard figures numbers but quite a few on here are obviously reluctant to accept them and instead choose to perform mental gymnastics so here I can give a solid review about the Switch numbers below: 

"Nintendo Switch hardware sales grew 115 percent compared to the same period in 2017." (Bullshit) 

"Lifetime sales of Nintendo Switch, which is entering only its second holiday season, have reached more than 8.2 million units." (Valuable)

"Sales of first-party games, including digital downloads, topped 1 million units Nov. 22-26, beating 2017’s totals by 78 percent." (Valuable) 

"Nintendo Switch games Pokémon: Let’s Go, Pikachu! and Pokémon: Let’s Go, Eevee! have hit combined U.S. sales of more than 1.5 million units since their Nov. 16 launch." (Valuable)

"Super Mario Party surpassed lifetime U.S. sales of 1 million units, becoming the fastest-selling game in the Mario Party series" (Valuable) 

"It became the best-selling Nintendo console in U.S. history for that five-day period, surpassing even Wii system sales." (Bullshit) 

I'm pretty sure you can now understand why the first and last statements are shitty since their not of any value when those statements aren't quantifiable while the statements in the middle are of value since it gives us arguably precise data and it's well implicated that Nintendo collected data up until the 26th of this month so the only true statement is that the "Nintendo Switch sold over 8.2M units on November 26 in the US" while the first or last statement is just useless crap ... 

I'm really curious to get some actual numerical analysis from the people who think that the 8.2M LTD figure really includes all of November up to Cyber Monday.

Remember:
Wii sold 500k on Black Friday alone in 2011, so Switch must have sold more than 500k in those five days.
Switch sold more than 200k at Best Buy alone between November 4th and the day before Thanksgiving.
Whatever Switch sold during those five days, it sold 53.5% less for the same period in 2017.
LTD at the end of October was 7.38M, so the sales between November 4th and Cyber Monday (according to you) must be between 0.82M and 0.91M.

Have fun reconciling those numbers.

Just out of curiosity, where did you get that data?

Actually, it might even be between November 4th and November 17th, since he said it sold more than 200k outside of Black Friday week.

I don't see any mention of best buy at all, he's saying based on his data switch sold more 200k in the US before that black Friday period.
