So the league you're in (gifted/masters) is dependent upon your hidden ranking. The rank you see on your profile is dependent on a so called "activity" ranking. The more you play/win the higher you get on that ranking in your profile.

The reason you jumped from gifted to masters wasn't because you were ranked #1 in your gifted league, but because your hidden ranking finally crossed a threshold that designates which league you should be in.

No one knows the hidden ranking algorithm or thresholds. Your profile ranking has nothing to do with your hidden ranking.
