The number is 40%, and it's 40% of code written by Copilot users. It's also just for Python:

> In files where it’s enabled, nearly 40% of code is being written by GitHub Copilot in popular coding languages, like Python—and we expect that to increase.

I wonder if this properly counts cases where copilot writes a bunch of code and then I delete it all and rewrite it manually.

From what I remember they check in at a few intervals after the suggestion is made and use string matching to check how much of the Copilot-written code remains.
