$39M x 0.2811 = $10.96M
$25.2M x 0.6392 = $16.11M
$18.6M x 0.6723 = $12.5M
$14.1M x 0.6601 = $9.31M
$15.3M x 1.1053 = $16.91M
These five average to $13.16M, with Tuesday's screenings making 24.8% of that figure, or $3.26M (though I'd consider it part of the regular previews, as anyone who'll see it on Tuesday would've seen it on opening night regardless). For reference, the first one earned $8.75M in its previews.
3 days ago it looked like this:
So I was going to make this follow-up yesterday but decided to give it an extra day to balance out after the big spike on Saturday. And well, it did pick some more steam, going up again on the average. Now another thing that can give us some perspective on how it trends is the new addition of how much the other films sold for the same day before release, and it looks like this:
146 (tickets sold that day by Crimes of Grindelwald) / 200 (tickets sold that day by Black Panther) = 0.7300
146 (Crimes of Grindelwald) / 305 (Infinity War) = 0.4787
146 (Crimes of Grindelwald) / 264 (Deadpool 2) = 0.5530
146 (Crimes of Grindelwald) / 151 (Solo) = 0.9669
146 (Crimes of Grindelwald) / 220 (Fallen Kingdom) = 0.6636
Basically, its closing fast on Solo, while losing ground very fast to Fallen Kingdom, which confirms our assumption that it won't be another outlier. With that in mind, we could average just Black Panther, Infinity War, and Deadpool 2, which turns out to be $13.19M, compared to the overall average of $13.16M. Makes sense, both of the outliers cancel each other out, but regardless I think that's the number to watch, as its far less volatile without the outliers.
Anyway, $10M+ previews is looking pretty damn good at this point, and I think there's a decent chance of Thursday alone going over $10M. If I had to put a number to it right now I would say around $11M-$12M, as I'm still not confident on it having great walk-ups, but with a 7x multiplier (the original had an 8.5x multiplier) that brings it to $77M-$84M for the opening weekend, which puts it handily over tracking.
I'll probably make another follow-up in a couple of days.
