If you are following the conversation you will know that this is the latest information:
Well, at least you've counted the emission from launch until now twice. 13.6 is the total for the entire series, so the 6.6 (or at least the part of it that was created according to the current formula) is already included
No, I didn't.
13.6 is the total for the serie from the first decline (when reward become 5*13/14) till infinity (not till 2050 because we used to say "total supply").
I can't count the emission when there were bugs. That's why I counted total supply as current emission (6kk) + supply from the first decline till infinity. So only the part of this year from decline till now was counted twice and that's 0.7kk approx (min).
P.S. "// yearly decline of production by 7.1% per year, projected 21.3M coins max by year 2050." - here goes "max"

Yeah, sorry, I corrected my post while you were replying, here's my adjusted version for readability:
Instead of the current supply, you would have to add the supply at block height 210240 to the series, which is 5 million according to
https://chainz.cryptoid.info/dash/block.dws?00000000000ae5b7e33558e0601f8f1c5cacc6dbc48ac5f90289d71609fa6355.htmSo that would bring the lower bound to approx. 18.6. Theoretically 10% of the future supply may not get issued since it it reserved for the bugeting system and if there are no proposals, those 10% would not get created. But even then, total supply would be above 14.
The minimum will appear to be 18.6 millions, while the first page state 14-18 million. As normal there is no clarification about this from the Dash developers because they do not answer questions when they do not like the answers
