Note:
I am going to keep update the thread in next 2 months to see which sort of changes of merit distributions from merit sources (especially when bias-effects from the Art contest cool down - after the vote, after congratulations.

ABSTRACT

The forum users distributed 8659 merits more what they usually did in most of half previous weeks at 4521 (the median of weekly merits).
There is nearly 292% increase in the total merits last week, compares to median of weekly merits (before 2019w46) at 4521.

We all know that theymos sent thousands of merits in his merit sprees.

From my discussion with @fillippone, I ask myself that are there any significant effects from increased reallocation of merits to merit sources?

In my Merit source observations, you can see despite of decrease in total merit sources (from 130 to 90 then increased to 98), the total merits per 30 days rose (from 20895 to 21671).

I scrap data from total merits theymos sent in the last week (only last week) in the 10^th anniversary Art contest.

He sent 9413 merits in total, from 18/11/2019 to 22/11/2019, forum time; but I stop counting his sent merits after November 22, 2019, 09:37:48 PM (when he locked that thread).

Code:

   +--------------------------------+

Those days fit well in the period of the last week, 2019w46, that has 14251 merits distributed in total (see in the 3^rd in column of weeklyrank.

The 2019w46 is from 12/11/ to 18/11/2019,, in GMT time (not forum time). So there is a little lag (hours) between two datasets. However, I don't think there are significant difference (hope that I am not wrong). See

What does it mean?
Only merits theymos sent on 18/11/2019 belong to the last week.

The median of weekly merits on 2019w45 (before the last week) is 4521.

Quote from: tranthidung on November 18, 2019, 03:14:04 AM

4521 is the median - p50.

Code:

To sum up:

In 2019w46

Total distributed merits: 14251
Total merits sent by theymos: 1071
Median of weekly merits before the last week: 4521

A raw caculation from merits (with all possible effects from Art contest - excludes theymos' sent-merits, new merit sources, newly increased sMerits allocation, and the others), we have:

Code:

. di 14251-1071-4521

Unbelievable!

It means that the forum community were extremely active last week in the way they use their merits. They sent 8659 merits more than they usually did in previous weeks (at 4521, the weekly median).
