So say if i won a dude 5 times in a row and i need 5 games till next belt, next round i win him does it take 5 games till my rank off?

uhm listen : streak shows how much games you won in a row them give NOT any qi more. youll get 1qi per win all the time expectly you buy a qi booster then youll get 2qi per win.
and the rank is a complicated thing in tb : maybe you have seen some green/blue/brown belts with ranks like 500 or? the rank shows how much qi you have on the belt. example : a greenbelt can be rank 1 because he have the most qi from the greenbelts (199 qi if im right).

Mongious, your anwser about the rank is totally incorrect.
It doesn't mean you'll be ranked"1" if you have 199 qi.

Some of the users have 199 qi right now, but they are not ranked "1"
Imagine that there are 10 players that have 199 qi each.
Not all of them will be ranked "1" will they?

Well, the rank does show how close you are to your next belt but, skill is involved aswell.

When there many players with the same number of qi, the ranks are also based on win percentage.

Incorrect, you don't have to win to get QI. You only have to play.

Win or lose, you still get QI.

Qi is like the games you played -snip-

Snipped the irrelevant part.
