Yes, data distribution does change overtime, although not significantly for all ranks nor combinations. For example, if you delimit the dates to last running month (25/07/2018..24/08/2018) and compare the data to the full history aggregate we can see that:
- Legendary (From Rank) barely has a variation of over 2 points in the sMerit awarded to any rank (in an other context 2 points is massive- i.e. sales, but not here).
- Hero on the other hand goes from awarding 19,81% of its awarded sMerit to the Member rank (Overall historical view), to 11,69% (one month view). Thats over an
eight point decrease there. Heros assignment to Jr. rank goes from 6,13% to 10,11%, nearly
four points increase more.
The above shows that distribution shifts overtime, partly due to causes I pointed out before, and that is why I would favour a view of last running month as a more accurate view (more aligned to day to day nowadays awarding habits).
Recently I created a topic called
sMerit Senders & Receivers Weight of top 100 and 200 weekly contributors. There we saw that the weight of the top 100 sMerit senders is massive (between 60% and 65% of monthly awarded sMerit as of late). Merit sources are likely within that group for sure, so taking them off the equation only covers 35%.40% of awarded sMerit by non-Merit Sources. The weight of Merits Sources is unfortunately such, that not considering them in the from/to rank sMerit awarding scheme would be a massive reduction from reality in my opinion.
On the other hand, If there were to exists a 100% non-equivocal list of Merit Sources, we could consider creating a flag to allow them to be filtered in/out (although you cound not distinguish between personal sMerit and source sMerit being awarded). Nevertheless, I can guess from the top 100/200 some of them, but not all of them (I often appear on the list too, not being a Merit Source).
