Farewell o_e_l_e_o

The table updated a little bit. Initially, I got the top 1% by their ranks, so 11537*1% ~ 116 (that figure you used) but then I realized there are two users have same total earned merits, so I turned to use the cutoff for the top 1% by their total earned merits >= 645. After all, there are 177 users in the top 1%, not 116.

Fortunately, results don't change too much.

I have what you need too (I did not totally understand what you ask for in my previous post).

Code:

     +---------------------------------------------------------+
     | temerit_group   totalmerit   pemerit_group      group50 |
     |---------------------------------------------------------|
  1. |         20405       433079             4.7   50% bottom |
  2. |        274318       433079            63.3      50% top |
  3. |        138356       433079            31.9       1% top |
     +---------------------------------------------------------+

Your roughly estimations are not too different from correct ones. Congrats! Cheesy

Another shocking fact, the top 1% richest in term of total earned merits own 32% of total earned merits in the forum, on the last week data dump by theymos. And, the richest will get richer more fastly than the others.

Fortunately, if one can manage to earn around 8 merits per week, that one will surely move upwards to the top, after months. Because of the top 100 merited users (take at 2019w36) earn about 8 merits per week, in median, over 27 weeks (2019w23 to 2019w49).

That was fast, thanks.

I think the numbers I'm looking for here are

Number of merits owned by the top 1%: 116 * 1187.2 = 137,715
Number of merits owned by the bottom 50%: 5949 * 3.4 = 20,227

That means the top 1% of posters combined possess 6.8x as many merits as the bottom 50%.

The bottom 50% have less than 15% of the top 1%'s ownership.

Furthermore, the top 25% of the top 1% still possess 180% more merits than the bottom 50%.

That means that 29 members together have almost twice as many merits as 5,949 combined.

Its not fair that in this great society, half the accounts on this forum should be expected to live on 9 merits or less, especially when 9 merits isn't enough to earn a Member level status.

If I am elected president, I will pledge to fight merit inequality in a system which disproportionately favors the merit rich and punishes the merit poor. Thank you for your vote.

You got it.

What is the number of merits earned by the top 1% of the 11,537 legit users as compared to the bottom 50%?

I'm trying to do some Bernie Sanders math here.

Farewell o_e_l_e_o

From this (Merit - simple poll on operational fundamentals), I create this one.

Users who have recorded activities with merits: 39341
users who sent merits only: 7398
Users who received merits only: 17922
Users who both received & sent merits: 14021

From that 14021 users:

Autobanned: 2470
Nuked: 14

Then we have the rest of 11537 legit users who both sent & earned merits and have not yet been autobanned or nuked.

See details here

Now, let's move further by looking at only the 11537 legit users' merit history.

Merit sent activities:

Means +/- standard deviation: 21.5 +/- 153.7
Median (interquartile range): 3 (1 - 6).
Minimum - maximum: 1 - 5088.
Total sent merits: 472 545.

Code:

    variable |         N      mean        sd       p50       p25       p75       min       max
-------------+--------------------------------------------------------------------------------
       nsent |   11537.0      21.5     153.7       3.0       1.0       6.0       1.0    5088.0
----------------------------------------------------------------------------------------------

Merit earned activites:

Means +/- standard deviation: 19.5 +/- 81.4
Median (interquartile range): 3 (2 - 9).
Minimum - maximum: 1 - 2394.
Total earned merits: 433 079.

Code:

    variable |         N      mean        sd       p50       p25       p75       min       max
-------------+--------------------------------------------------------------------------------
     nearned |   11537.0      19.5      81.4       3.0       2.0       9.0       1.0    2394.0
----------------------------------------------------------------------------------------------

In a nutshell, we have the medians at 3 times (from the sample size of 11537 legit users).

The upper population

Let's assume users who have stats >= p50 (for each stats) are more active ones. I skipped data for that p50-above population, to see how stats change.

The results show that:

The upper population have nearly double statistics compare to the whole population.
The upper population have 5776 - 6922 users only. You might be shocked.
