The article says (2nd paragraph, last sentence):

> Out of the billions of legitimate payments made on Stripe, Radar incorrectly blocks just 0.1%.

I seem to parse this differently, to me it reads as if 1 out of 1000 transactions are incorrectly flagged. I am not a native speaker though. Could you explain how you arrive at 0.1% of blocked transactions?

I just saw your edit, but my question still stands.
