If I understood those 2 examples correctly, in the one with the much higher increases, each day would be priced separately, so you could have a trip with tickets in more than one category during your stay. In the other one, every day would be priced at the rate for the day in your stay that is in the highest tier. That doesn't appear in the charts themselves, but in some additional information I saw, I think in the WDWMagic and Touring Plans articles. Someone can correct me if I'm wrong.
But, to me, the important thing in the first chart listed above is that the difference between the Bronze and Gold tiers is not that great. So, an all Gold trip would not be that much more than an all Bronze trip. Again, using the example of the 7 day hopper, the all Gold would only be 10% higher than all Bronze. Nothing in that chart would produce anything remotely close to a 50% increase, much less an 80% increase.
I don't believe for a second that Disney is going to be able to fool anyone by obscuring much higher prices with a tiered pricing concept. First time or infrequent visitors don't care how much prices have increased, they just want to know what they are NOW. And then they can decide what they are willing to pay. And I'm sure Disney knows that increasing any prices 80% from their current levels is going to affect buying decisions for a lot of potential visitors.
