It seems you've found the algorithm right there. Not only is this algorithm the good old mega-nested-if-test-of-hard-coded-answers for a few of the questions asked. It basically checks if you think you are at risk, then puts you "atRisk" if you are older than 56/about to retire/an immigrant/pregnant.
Sadly; that is probably enough to report relatively correct values.
