For some? Yes. Overall? No. The AVERAGE wait is the same. Which is the whole point of this thread. The average wait across all guests is unchanged.
Take these two number sets:
A) 10, 10, 10, 40, 40, 40, 50, 60, 60, 60 Total 380, Average 38
B) 30, 30, 30, 30, 30, 40, 40, 50, 50, 50 Total 380, Average 38
If those are wait times. And you are a park operator. And you can choose for every 10 guests to experience Set A or Set B. Which would you choose?
A) First 3 ppl averaged 10 min. Last 7 ppl averaged 50 min.
B) First 3 ppl averaged 30 min. Last 7 ppl averaged 41 min.
Set A involves 3 out of 10 people riding very quickly, but most people waiting a long time. This is akin to FP-
Set B involves everyone waiting more or less 30-50 minutes, for an average of the same 38 minutes. This is FP+
Now, imagine EVERY time those ppl go on a ride, the times are the same. As you can see, the first 3 ppl in Set A rock out on FP-, waiting 10 min PER RIDE. But the last 7 wait extreme times over and over.
If you were one of "the 3" who used FP-, FP+ sucks for you as your typical wait goes up from 10 min to 30 min. But if you were part of the majority 7 people, your average wait went down from 50 min to 41 min. Over the course of say 6 rides (picking 6 as 6 would be 6 FP- for a good FP- user and 0 for a non FP- user, or 3 FP+ and 3 via non-FP+ in the new system) that saves those 7 people about an hour per day!
(It costs the first 3 ppl a boatload per day - but, 7 are happier and 7 is more than 3).
The AVERAGE time waiting is the same. It is only who is doing the waiting that is different.
