if you are seeing 900% productivity gains, why did these controlled experiments only find 28%, mostly among programmers who don't know what they're doing? and only 8–10% among programmers who did? do you have any hypotheses?

i suspect you are seeing 900% productivity gains on certain narrow tasks (like greenfield prototype-quality code using apis you aren't familiar with) and incorrectly extrapolating to programming as a whole
