Good explanation. Thank you.

In December 2016, the inflation rate was set at 9.5%, after a continuous decrease of 0.01% every 8.68 days (0.42% decrease every year until reaching 0, 95%), the current inflation of Steem Blockchain has reached 6.828%

I agree with your calculations here. If I take HF16 (Dec. 6, 2016) as the start date and plug the numbers into a spreadsheet, here's what I see for April, 2023.

Interestingly, though, it's not actually what I see when I look at the current supply (or virtual supply) numbers from SteemDB.io, here. From March 29 through April 22, I see an average APR of 6.719%...

I guess part of the difference is from the #burnsteem25 campaign, and another part is the SBD funding for @steem.dao - since SBDs don't effect the current supply measurement. Also, we know that the virtual supply inflation rate can be influenced by the price of STEEM. Not sure what other factors are in play, but the point is that actual inflation measurements may differ from the blockchain's default rate.

If you look at slide 4 in this series of posts, you can see the measured value that I have calculated from SteemDB weekly from November, 2023 until now.
