By saying drop dramatically, I meant the fall since the all time high of weekly distributed merit, above 9.6k, LOL.
Merit distribution is back to the long term "bottom", after a sharp peak 8 weeks ago (largely because of abuse) when the new Jr. Member restrictions were implemented.
There was however a large Merit source removed in the past weeks.
In the attached image, the percentage drop of the last week compared to median (of weekly distributed merit since 5th of March) is nearly 24% [3320 compared to 4405].
Weekly update on merit distributions since the 5th of March.
As I posted previously, the normal range of merit distribution is from 2.5k to 6.2k.

In a nutshell, weeks that have total distributed merits above 6.2k or below 2.5k should be taken into consideration because they are highly potential outliers. It is probably that the sorts of outlier-weeks occur due to significant changes in the forum rules/ systems, etc.
Of course, the exact value of outlier thresholds, both above and below, will change over time, but it will be somewhere around those points (2.5k and 6.2k).

In my opinion, the median, which fluctuated around 4.4k, should be use as a gold figure to measure changes of weekly distributed merits. Medians are recognised as nearly true means, more closely to true means, and should be used to have more exact overview.
