I have long advocated the following.
The Thursday pre-opener numbers are throwing off the adjust prices.
Not all movies perform as well on Thursday pre-openers. While GFB movies do very well, adult marketed dramas and animated films not so well.
My suggestion: change the formula to be (Fri-Sun)*2.7 plus previous. That way, the pre-opener does not get multiplied, and we get back closer to the delist price. If it is a holiday weekend, 2.2 times the weekend plus previous. If a Thanksgiving movie has a pre-opener, a simillar formula.
As to Christmas, there are 3 wide movies opening this year. I would be willing to try the experiment of no .OW, .PU or .CA for that weekend since there is no formula to apply.
Want to have fun? Try 2 weekends for the derivatives. Let them halt on Christmas Eve.
BUT DO NOT THROW AWAY the regular adjusts.
Like HSX Orange, it will drive people away from the site.
