Not sure who you are replying to or if there is a question here.
I think we answered the question you had on 4-12-2019 in this thread. What kensabre posted above is his tin-foil hat conspiracy take on WGT, but most of the players don't subscribe to that at all.
I guess your 2017 post was about testing your computer speed for Flash and it seemed to do well. That is one thing to test, but there are so many things that cause slowdowns and/or meter issues that have nothing to do with WGT. Most of those issues are related to something happening between WGT servers and your display. It may be issues with bandwidth with your ISP, computer or Flash caches, memory overloads on your computer, browser issues, Flash issues, and many other things that WGT can't control. Sometimes they are due to upgrades in a browser of Flash that you may not even know have occurred. There have been a number of threads where people have discussed some of these and I can't recall them all. I think some were in this subforum but also in other subforums.
Good luck with tracking down these issues.
