Very interesting indeed! I would also have expected things to be more static. 

It'd be inteteresting to add in a further layer about how often new people enter the top 20. Or something on how often there's change of the top 20 rather than change within.

Great analysis as always!

Hi @crokkon

Great work on building your own dataset for this (another!) analysis, some history I would like to be available in SteemSQL isn't present and DIY is a good alternative for sure.

>  personally perceived the witness ranking list as rather static, at least in the upper positions.

Same.  The gaps in MVESTS between the top 10 being much larger than lower down the ranks, although individual accounts voting in the top 10 do hold large, vote-swinging stake.

> I have not correlated the changes with blockchain "events", but I'm pretty sure there would be connections to announcements and posts.

In the case of @therealwolf, I think the state of the dapps work may have cause some good publicity, and a move on this witness.

Being a witness and lying outside the top 50, I would selfishly have liked to see this expanded to top 100/all witnesses, but understand the addition effort being quite sizable.  Also, your original idea may not have been looking at lower ranks, and so I understand the scope not including all witnesses.

Cheers

Happy New Year!

Very interesting content. Thank you.

Intuitively, there seems to have been more fluctuations than usual after the plunge in STEEM prices.

In my memory, there is usually a change between 17th and 22nd, and sometimes one or two TOP witnesses seem to change.

Other big fluctuations seem to be rare. The long-term influence of top-witnesses, the strong influence of freedom and blocktrades accounts seems to be the main reason, and mutual voting among top-witnesses seems to work partly.

Stability of witness status is an important factor in job performance, but since their term is not fixed, more active ranking changes seem desirable.
