potential activity = max activity (increases by 14 every 2 weeks if you made a post in that time period.).
What I don't understand when will it become sr. member or so.Is there a calculative timeframe?
get the current potential activity using some service (I recommend
this one) then look at this
list of activity periods start dates.
I didnt understand the first chart, thanks for the second one, its really interesting, good to know my potential profile
