Well, I wish it was my own report this time but it isn't. Instead I'd just link to this little experiment. As mentioned in the comments it is not a statistically proved result but I still think it's good that somebody took their time to add one more data point to the overall statistics. Hey, it inspired me to do that too. Well I probably can't do the same detailed story point per hour thing but I should be able to at least count the number of bugs found in different areas of the code and compare that to complexity and test coverage. No idea if that is interesting but it might be something. Just hope people with more data publish it even if not what they want.
