One thing to note is that the risk factor surfaced in the dashboard is the primary risk factor, but the final risk level is a combination of many different factors--it's not accurate to say that the charge was blocked only because the card country did not match the IP country. That said, if you are certain that there are areas where there are high numbers of false positives, Radar does provide tools for making corrections (by writing rules to allow or send charges to review, for example). I'm happy to talk more about the specifics in your case if you send me a note (and definitely let me know if there's a way we can make this clearer in docs/product) -- I'm tara@stripe.com.
