That is nearly impossible, as already explained by the above members. Aside from the merits generated a month from merit sources, the Smerit gotten from other members who receive merits still generates a lot of smerit when they are being distributed. Just as you have also explained, if everyone is distributing their merit and not holding back, I believe that alone can go a long way compared to the amount that is being distributed by merit sources every now and then. It's nearly impossible, as all this possibility has been calculated in the past before the merit system was introduced.
