Last year, all the movies either opened on Weds. or Sat. (Christmas Day) and in 2016, the last time Christmas fell on a Sunday, Why Him? was the only movie to open on Friday with Thursday previews. That had a 11.3X mult but this year's Thursday previews started earlier and probably more interest in them (Whitney and Babylon) so that they could be more like 10X depending on whether business drops a lot on Sat (for Xmas Eve)... Still, I'm going with 10X give or take once Thursday #s are reported.
