"we issued more than 660,000 challenges, of which only 0.32% were solved — meaning our algorithm detected bots with a 99.68% rate of True Positives."

Isn't that a bit optimistic? The captcha might have driven people away. Especially on mobile i'm not too keen on clicking photo tiles containing storefronts. Is there a way to detect false positives?
