so if you have no more sMerit left, then I guess your monthly "sMerit allowance" is 94
I think all sMerits of Merit sources are numbers divisible by 5 (the number's last digit is either 0 or 5,) corrects me if I am wrong.
Or you might check PM of theymos when he was add you merit sources. Then you will find which date you have been added. Then you might calculate how many smerit allocated for you. But you need count manually.
Even using this method you can't be accurate unless you spend all your monthly points.
I was given a reply via pm I am 25 a month.
I thought that the minimum is 50, there seem to be some sources getting thousands of sMerit (131 merit sources & 21045 sMerit per 30 days.)
