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.
