That 55% seems to be from here?
https://github.blog/news-insights/research/research-quantifying-github-copilots-impact-on-developer-productivity-and-happiness/

They're comparing two cohorts on how long it took to complete a well defined task with Copilot vs without, so yeah with the automatic suggestions that it produces, that feels like a somewhat plausible number for a specific coding task. They're not claiming a 55% efficiency gain across general overall monthly productivity though, that'd be a ridiculously high.

Overall productivity boost is tough to quantify because tasks aren't always well defined, and nobody is coding every single minute of the day, but even tiny boost may be enough for a subscription to pay for itself. 🙂

cheers,
Tony

Thanks Tony GitHub claims 55% efficiency for devs gained do you agree? If not what % would you give it for day to day dev work?

We’ve given it a 1-2% at the most.

    Copilot definitely isn't a magic 'do my job' button, and likely
    won't ever be, or that job would simply no longer exist.

    It does take care of a lot of the busy work though, and isn't just
    for Intellisense like code suggestions - you can happily converse
    with it in the chat window about high level topics and refine the
    context incrementally, generate boilerplate json/bicep/scripts
    from a few lines of prose, or highlight a non-trivial block of
    existing code and ask it to explain/summarise or find issues.

    While it's not HAL 9000 I reckon it comes pretty close, and quite
    importantly hasn't tried to murder me (yet).

    Before my trial I was skeptical about how much value it would
    provide, but was pleasantly surprised enough to hand over 15
    dollarydoos each month. 😎

    When I first saw the movie /2001: A Space Odyssey/ in 1969 I was
    fascinated by HAL (I was clearly destined to work in IT!), and
    now 55 years later I'd like to be able to sit down with HAL and
    explain some complex business requirement to him, converse like
    professionals and weigh-up the pros and cons of different
    platforms and languages based upon his world of experience and
    get him to code like a 1000x developer and generate a complete
    working skeleton of the required product. When will I see that?
    I'm a bit disappointed so far.

    Oh well, back to coding with my Copilot buddy.
