Yes, I quoted that site to a lady a couple of weeks ago.
I can tell you that the actual decision engine is a lot more complicated than that chart would lead you to believe. The gloss they lay out is very incomplete. I can tell you that you do get points for being a professional and having a good education. Who would you rather lend money to, a guy who worked at McDonald's or a surgeon?
I'm not at liberty to say more because of circumstances and I can't specify exactly how many points you get for being a doctor as opposed to a collection agent (let's hope it's quite a lot).
