<...>Even better: correct it for Merit per post instead of Merit per Activity<...>
Infact, I did that a couple of days ago, for all profiles (with a few restrictions) although I diluted it into somebody elses thread, as it was an answer to @DooMADs question on the matter. I did delimit the window frame to the last running year, to get a recent reading of the ratio merit/post (see:
re: I received 1 merit for exactly 10 posts on average). @fillippone complemented the information with a nice chart on that same thread (see:
re: I received 1 merit for exactly 10 posts on average).
