Not too mind blowing when you take into consideration the fact that Hollywood Drift's construction was much much much more complex than the other 3 coasters. Orlando's Hollywood Drift is entirely on flat ground with no actual building obstacles for them to work around. Montezooma's layout is super small and simple (and if we really want to get technical, they've been working on that project on the ground for far too ridiculously long), and Project Purple (apart from the upside down LSM's) is another coaster on flat ground with no obstacles to worry about.
