I see this article that says
After a hidden period of time, their skill level will be reevaluated.
Has anyone been able to determine how this work? I now reached 1st place in my league and am eager to pass on to the next. I was already promoted a league once, how long do I wait before being promoted again? Does a higher score grant me a better/sooner chance of being upgraded, or does it simply happen at random time period if I have enough score?
