Congratulations to the new Merit Source, now they are
83 
However, based on the analysis of @coinlocket, I guess merit sources have not used all their sMerits.
Of course, there are several reasons:
1) There are not enough merit-deserved threads. Spammers have kept spamming the forum in alt child boards, etc. Cheaters have still earned money from their spamming threads. These sort of low-quality users contributed to the un-used sMerits of merit sources.
2) Merit sources might be busy some day, at some extents, hence they might not deliver all their sMerits away.
Anyway, it's good to know that total numbers of merit sources in the forum increased.
