You can see my earlier comment somewhere here, but I feel obliged to remind everyone that the claim that Github Copilot made developers "55% more productive" came from a study where they asked 100 developers to implement an HTTP server in Javascript, split the group up roughly 50/50, and gave one group Github Copilot. The Copilot group did it in an hour and 11 minutes, whereas the control group got it done 2 hours and 41 minutes.

That's where the 55% number is coming from. It's coming from this experiment, and only this experiment.

So yeah, if you're wondering why you aren't somehow 50% more productive when using Github Copilot, it's probably because you're not implementing a simple task that's been done to death in countless tutorials.
