"I originally said they do 7 shows Christmas Week and 9 shows New Years week. I noted where some of them do it the opposite." Of the shows you mention, unless I counted wrong (quite possible) not one had a 7 show christmas week and a 9 show New Years. Christmas is the big money week, not New Years.
Only three shows had a 9 performance Christmas week and 7 performance New Years:
Gentleman's Guide, Mamma Mia, and
Phantom.
Five shows added a 9th performance Christmas week, but had a normal (possibly rearranged) 8 performance New Years week:
Kinky Boots, Lion King, Newsies, Rock of Ages and
Wicked "I don't know about the financial arrangements, but since it's usually just a case of switching a Tuesday night show to Sunday night instead, it's not really that difficult to do. And they could sort of all out with Equity ahead of time." There are several other unions to consider, but in any case switching any days around within the mon-sunday payweek, as long as there are still 8 shows isn't a big deal, and that's what
After Midnight, Jersey Boys, Matilda, Motown, Janis Joplin, and
Pippin did - they all had 8 performances at Christmas and 8 performances new years. They just rearranged the schedule.
The odd shows out were:
Betrayal (did the 9 performances at Christmas and 9 performances new years)
Big Fish (9 performances at Christmas, closed dec 29th)
Machinal (7 performances Christmas, 7 performances christmas)
tl:dr?
Adding a 9th show is doable but very expensive. You can't make it up by taking away a performance the previous or following week. The producers gain nothing by losing a performance. They still have to pay cast and crew for it.
eta: did Machinal only have a 7 performance week for the run?
