I found this website while googling for "credit scorecards". You put in your FICO score and it matches/recommends, what cc's are most appropriate for your score.
Maybe they are just being conservative, to be safe. I dunno. I guess their reasoning is: better to put in high scores instead of lower one's(to not artificially raise someone's expectations of being approved for a card they can't get)
This is fine as long as your scores are close, however mine range from 688EX to 604TU and 671EQ so witout know where they get their info from don't know if it's worth the inquiry if you may be denied!
