Nor UA, nor @steem-ua for that matter is "perfect". I've never intentionally labeled it as such either. Yet UA (as an influence metric) and @steem-ua (a curation system using UA data) do have "a place" on Steem, I think.
If you read back, I mean my initial "invention posts", you can see that initially I've tried to let others, preferably Steemit Inc. itself, develop UA and embed it both in the Condenser interface as well as "blockchain-wide". Yet some large stakeholders like it, others don't, other technological developments have/had a higher priority, and as a consequence I've joined forces with @holger80 to develop UA and @steem-ua.
And I think we so far we've done the best we could; the mere fact close to 900 individual accounts are delegating to @steem-ua is "proof" the program and metric have merit.
And as I've explained in this post, it's the "Steem-UA Power Delegators" that "carry" all those smaller delegators; providing them with higher upvotes than self-voting would bring them, and at the same time keeping them on-board on the Steem chain. That's worth a lot, I think. So if you support this mission, then feel free to become a "Power Delegator" yourself of course... Would be very much appreciated.
I totally agree that you guys have been doing good so far and I support the program. So you don't need to explain about it in detail :)
But I'm talking about the possibility of bug in the recent change.
Just see https://steem-ua.com/stats
surprised that you guys haven't fixed this yet. I mentioned this several times including here: https://steemit.com/utopian-io/@blockchainstudio/steem-ua-suggestions-optional-ranking-info-in-comments-delegator-pages-voting-conflict-prevention-for-utopian-posts (probably you didn't read this before)
There is a bug in this very simple thing. How are you so sure about more complicated algorithm? Personally I have fixed many bugs in several steem projects. Any program can have bugs.
For instance, afaik, top 100 witness's UA rank was usually higher than 150. But for instance, ayogom (58th)'s UA rank was around 100 but now 5265. This is just an example and there are so many cases like this. As I said many times, please make comparison table witness rank and ua rank, then you'll understand what I'm talking about. Again, it had been quite reasonable til a few days ago.
