Hi Raffles. I completely understand your perspective however it is not quite correct because the instrumentation and measurements for this test are not well enough refined, as I think I've highlighted in the post.

While false positives should be measured against the entirety, in this test they are measured as a percentage of a number of false positive tests. For perspective, it was one false positive on one file that was only ever seen in one place and could have only ever affected one user. That is a very different thing than .33% of all things are false positives.
