> The challenge is compounded by the fact that fraud is rare—on the order of 1 out of every 1,000 payments.
So 0.1% of 0.1% (0.001%) of transactions are incorrectly blocked.
> 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.
What is interesting is how they determine the incorrect blocks but the article doesn't really expand on that, it's just about one aspect of their fraud detection pipeline.
Or rephrased:
"Stripe wrongly blocked millions of payments." What a headline!
Let's see which news outlet will use it.
