Rankade is good for anything, but it's not the best tool to manage the performances of single players in a fixed-team tournament (e.g. a soccer round-robin tournament).
Of course you can register the results in rankade, but you already have the official rankings who tell you who the winner is.
Rankade is very useful, however, if you play with teams that change within a (fixed or variable) group of people, or if you want to track players' skill in a club with tournaments on regular basis.
