Yeah... sure, there's a particular way it's being calculated and it's simply the same way you've heard almost everyone say...
You seeee.., when I got registered in here, I initially had my activity to merit ratio getting too aligned, so I was told I had a decent history.
I didn't actually know how the whole thing's been calculated honestly, I only thought it'll be cool and even more decent to keep the 12 merit -12 post -12 activity ratio.... I think this particular topic is been clearly explained on one of the intro threads, read them.
