I have not tried to do the math behind how many fastpasses, tiering, etc. but there has to be a limit. Consider that with the new system everybody will be selecting fastpasses (many did not know about of use fp-) and if fastpasses per day were to increase to 5, 6, 8, 10....that is essentially equating to ZERO fastpasses. The fastpass lines will get longer and longer and overtake the standby lines. So I may agree with you that 3 fastpasses may be a little short at magic kingdom but you realize there can't be that much more. Also the tiering may have to be necessary too. Roughly 30,000 people visit a single Disney park per day. Without tiering maybe 20,000 would all choose Soarin and Test Track. Again, fastpass lines would be huge and no longer fastpass. I believe we have to consider this reality when we complain about tiering and only 3 fastpasses.
