Hiring and funding from the stored fields add up to +1. The stored score of 4 includes a judgment call the fields don't capture (often a boundary month or a round we don't count), so traction and red-flag points can't be split out exactly.
Distance (10K) is a separate read on how long the lead can last. It doesn't change the score.
