"Inconsistent startups write 3.4 times more lines of code in the Discovery stage and 2.25 times more lines of code in the Efficiency stage."

This is interesting. Either inconsistent startups (startups that are more likely to fail) over-do development - or - they tackle problems that are more complex and thus require more code. The implication of the later point is that startups working on difficult problems are more likely to make mistakes (like premature scaling) and fail.
