Yes- while "Real Time" is great- 30/60 and 180 day projections are even better. Universal has to upgrade their infrastructure before it can be close to what Disney's is. It will be easier, of course, due to the size and scope of universal vs WDW.
During the end of January- you could go to a relatively slow park that had a fraction of the July crowds- yet wait times weren't significantly different. Gone are the "walk on" days. Sure, you might find one here and there- but analyzing the wait times for 2015-2016 since the implementation of tiers and MM+ having years of data- there is no discernible difference in the amount of rides one can do on January 25th vs July 25th. Try that at Universal. Or Try that at Disney in 2013. And it's all money saved on the back-end. Just 1 side of Dumbo running until 11am-12pm. Just 2 cars running on BTMR or Everest. A severe cut in staff for x park on x day or x restaurant or x store. Less fastpasses available for slow days, etc. The projections are incredible and again- in analyzing the wait times- its remarkable how similar they are now (not taking into account ride closures of course).
That has never been the case before MM+. Now the best you get for a "slow time of year" are less crowded walkways.
No other park is a week-long destination. TDL is the closest they have- and thats 4 days max (literally- you cant buy a 5 day)
