The article says new tests, is that a test for a new person. Or simply a test in a certain time frame I assume it is the latter, which means the stats can be skwed somewhat. I can't say what degree it would be but I've had 8 tests. Which means I show up in the testing stats 8 times. My situation is somewhat unique, but I'm not alone. Hence the distinction I am curious about.
