The whole carb loading thing is misunderstood by most people. The attached link is a pretty good explanation of the various protocols.

The original carb loading protocol with severe carb restrictions several days before an event has a bunch of problems, not the least of which is that it disrupts your training, and therefore would only be useful for an event you really wanted to peak for.
The "Western Australian method" makes sense. But its really nothing more than do "openers" the day before the event, and then eat with a bit higher percentage of carbs the day before the race.
None of this is a license to stuff yourself just because you can label it "carb loading"
