Yes it should be logical merit decreasing every week, sMerit should always be less than the previous months merit sent because
Each 1 merit sent will produce -> 0.5 sMerit (like this week its 4544 merits awared, so total sMerits generated are = 2272 )
Only thing which can increase the Merits for next week will be Merit Source, now to calculate the merits for next week's formula will be like
Next week's maximum merits = (Last week given Merits /2 ) + Merit Source's merits
So in summary reason of this decrease:
- Merit sources did not increase for last few weeks
- Not all sMerit distributed which were generated from last week's merits
As theymos hinted Merit Sources will increase gradually.
Also if merits are in abundance and every next post starts getting merit, you will loose the beauty of Merit System. It should be less and should be given to well deserving posts only.
