The tables and chart on the
first page have been updated.
I also published monthly statistics for April 2019. Interestingly, the merit source
chimk is the leader of this TOP-200 in the previous month. Good work!

By the way,
d5000 confirmed to be a merit source in a public post. Thanks to
qwk for the info.

I will add them to the
full list of merit sources if the analysis detects them calculating their indicator "Generosity".
The analysis has detected
d5000 as a merit source, so I added this user to the list of known merit sources.
I can't find myself in the OP, can it really be right? I'm not completely sure so figured I should at least ask first.
Following from the BPIP, you have received 813 merit and sent 496 merit:
https://bpip.org/profile.aspx?p=HhampuzOP includes members to the list according to the "Generosity" parameter which is calculated by formula:
GENEROSITY = SENT_MERITS - ceil(RECEIVED_MERITS / 2)
Therefore, your "Generosity" = 496 - ceil(813/2) = 496 - 407 = 89, which is not enough to get into the list.
Veleor has explained this question very well.

is my userID invisible in whatever data you use to conduct these results ?

, i read the op trying to find any special criteria which i don't fit into,i couldn't find any reason why am i not being listed in the most generous merit senders despite the fact that I sent hundreds of them so far

You are in the same situation. No new criteria is used.
