Crowd Calendar for Christmas Week

Hello! I am noticing that for the week of Christmas, the Crowd Calendar is showing lots of 10s, but the wait times aren’t reflecting this. I certainly won’t complain about shorter lines, but it makes me wonder what is making those days be considered 10s if the lines aren’t going to be long for most attractions.

Christmas week is the most popular week in WDW. I’m sure TP is still tweaking wait times because algorithms are most likely changing due to Genie roll out, APRs, post Covid nuances, etc.
