If you do a search, you'll see both Terry's and the originator's opinion of the current MAP test...get the Toto, you won't be sorry. Manufacturers have learned how to maximize the test with the plastic wrapped paste. Nobody excretes stuff remotely similar. Plus, the average person doesn't dump anywhere near that much - 1000g is 2.2 pounds, about 9 sticks of butter end-to-end...that's almost impossible to produce. Toto does real-world testing, most of the others try to maximize the test results. They aren't the same.
