If there’s one thing that always annoyed me about the Github commit display it’s that… well, it displays commits, and not a much better (if not perfect) metric such as LoC. Depending on the feature or volatility of the branch my own commits can vary wildly in how granular they are.
Definitely. It's not indicative of any sort of quality, which naturally makes it fun to game! I randomized the amount of commits on each day so my graph has varying shades of color!
