The sales risk section is a bit off to me. It's possible for 5 to be true without any of the other stages to have ever occurred. That said, perhaps that's irrelevant.
Also, certain risks inherently trump others for early stage startups. Moving from a 3 to a 5 under Product/Market Fit is a much more ideal compared to moving recruiting risk from 1 to 3 or team risk from 1 to 3. (After all, it's kind of moot to hire full time employees for every area if you don't even have good P/M fit)
