Thank you for letting me know @abh12345 …
”I did take a brief look at this last month but didn't really come up with anything solid.”
As much as you’d make any future effort for my sake, though, I will spare you any further trouble …
”I think what I'd need to do is take a set of accounts …”
… as my request was based upon the apparent mistaken thought there is some way to gather aggregate data. For the entire Steem blockchain, for whatever date range one might choose. It is (unless I am badly mistaken …), after all, a giant database of sorts …
Short of that, how you would determine which accounts represented a statistically valid sample set would seem to not be possible.
I certainly appreciate you investing your time to respond to my request. Thanks again!
P.S. Got my hands full "out here," for the moment, but clearly need to catch up with what you have written somewhere, if you are soon to be between jobs ...
