I agree with this in principle, but honestly the sampled numbers can be really misleading. It all depends on the magnitude of your visits. If you ask for a year's worth of data for a company with 10 million visits for the year, you're going to get into trouble. This makes creating tools and automated workflows that use the GA API pretty hard. Sampling itself makes a ton of sense though, and its why Google can offer this service at the level of quality they do.
