Find our own threshold for Max Churn #98

Closed andymeneely closed 10 years ago

andymeneely commented 10 years ago

Look at the histogram of Max Churn and graph it against number of comments and messages. Does the participation drop off when churn gets higher?

Is there a clear threshold for when developers "burn out"? If so, determine that threshold and make a metric out of it. Maybe CodeReview#burnout?

Here's what a histogram from a few weeks ago looked like. Haven't gotten to the scatter plot yet.

@kayladavis Let's follow up with this question. Use something like Excel or R to construct a 2D plot of max_churn and comments as well as max_churn and messages over CodeReviews.

Don't worry about automating plots just yet (although that might be on the horizon)
