You want 1 smerit per day for all member accounts. That is 30 smerit per month. If someone has 3-4 such accounts, he will easily make the main account Senior member even with mediocre posts. This will make the merit system useless. It is better in the current way where the merits are generated each month for only the merit sources (who are really concerned about the forum). It does look like that current circulation of merits is not  sufficient and  thus admin should add more members as merit sources. However, I do not see senior members applying for this a lot.
