As suggested by Anthony I ran StatSVN against the entire moviestorm repository. 90 minutes later and we have a wonderful graph:
Now this is everything, not just code, but makes for interesting viewing. I've taken the names out in the name of decency, but I can reveal that the top green line is Ben_S, Capin' Dave is Pink, and twak the second green line.
Now ben manages his massive line-change rate by endlessly editing all our xml structures. But Dave is a coder and has written 300K lines of code - the length of the entire code base. I've written another 250K (altho mostly UI twaddle, so it doesn't count). I think we've written the code base two or three times over since we've started. That's quite some code churn!
Something to mention here is that number of lines does not map onto how hard we work or how good the work is. It's certainly not indicative of quality, and quite possibly inversely proportional quality. It's an interesting metric that seems to be fairly constant for each person - does that mean some people can do the same quantity of work with fewer lines of code?
In other graph-related news - the most likely time for us to commit stuff to the repository is 4pm on a Friday - "quick it's the weekend, commit it, cheese it and hope someone else fixes it before I get in on monday" ;)
Those long tails are what singles startups out from the crowd - no option but to get it done.
