Another way of looking at it:
5 day: USD 271.58 / 2950 = USD 0.092 / pt * 1.347 (current spot rate) = 12.4 cents / pt
7 day: USD 295.54 / 3250 = USD 0.091 / pt * 1.347 = 12.2 cents / pt
So the 5 day is actually a marginally better "value". Both are better value than, say, cash miles ($10 / 95 = 10.5 cents/pt). And the value is better still when you consider a typical USD "buy" rate rather than the spot rate. But there are better "deals", for example:
Universal 2-day park to park: USD 271.56 / 2425 = USD 0.112 / pt * 1.347 = 15.1 cents / pt
Of course, this only really matters if you're trying to decide between different tickets that you would actually buy otherwise. No good getting a great deal on Universal tickets if you really want to be at Disney!
The old Air Miles WDW tickets were actually a better $/pt value than the new discounted tickets, because the cost of tickets without the Canadian Resident discount was so much higher. Air Miles failed to pass on about 20% of Disney's discount, and these discounted tickets can't be price-bridged. But as long as you're happy with 5 or 7 day base tickets, then you're still getting them at a far lower absolute cost than you would have a few months ago.
