Probably not what you had in mind, but if there's a 0.1% that you have a bug in any given line (let's assume that includes bugs in how lines interact as well) - there's about a 63% chance there's at least one bug for every 1000 lines of code, if my math isn't off.
That's mostly to say: I agree with your assessment that you (and me and everyone) need help to review code and look for bugs.
