No there were math errors. Was it using statistical functions? I can't recall, I just know we had to double check everything.

    Yeah, some of the answers it produces are very questionable. The implementation of a lot of the stat functions is super-naive and not very stable in borderline cases. Take the standard deviation of three identical numbers, get an answer which is nearly-but-not-quite zero. They've also refused to improve their algorithms as it might break existing customer worksheets.
