edit: fixed autocorrects
I mean, looking through the git logs means you look at code contributions. If you're a software engineer, that's kind of, ya know, your entire jobs. You can get a lot from looking at someone's contributions, especially in code or documentation or slack responses. Volume doesn't mean shit though, that's the trick.

Yes, please.
Based on having studied lots and lots of open source projects, I can say volume has a very strong correlation with experience. The more people contribute, the more likely they have been contributing for a long time. A novice contributing a lot to me, can be a sign they are extremely good or they are trying to game the system or they don't know what they are doing and are constantly fixing previous mistakes.
