It’s been mentioned a few times. Check out this post:
re: who can award Merits. The formula in the code tells you how the default sMerits were quantified, based on rank and activity at the time. The amount therefore varied per account, and is not known publicly on an individual 1-to-1 basis.
According to the formula, the best case scenario (máx. Airdropped sMerit) would be:
Legendary : 1000 * 0,4= 400 sMerits
Hero Member: 500 * 0,35= 175 sMerits
Sr. Member: 250 * 0,25= 62 sMerits
Full Member: 100 * 0,2= 20 sMerits
Member: 10 * 0,1= 1 sMerit
