I'm kinda using both. TROS is performing a bit like both except for the weird 50+% drop on Christmas Eve for Anchorman 2, and it obviously will not jump 188% like that did on Christmas Day.
Desolation of Smaug seems to be a pretty good comparison so far. The biggest deviation will be Boxing Day. Smaug jumped 76.7% on Christmas Day, then a further 13.1% on Boxing Day Thurs. Now I wouldn't have known any better than to go along with that but tracking here suggests that's not happening for TROS, nor will it jump quite as high as 76.7% on Christmas Day. Could jump as high as 70% though.
