Preparing for the "Van Kanegem" tournament.

And there's no need for a universal ranking system. The point is that some players are good at one version, others at another. But there's no overall rating. In this tournament, I suggest creating parameters in the final table to reflect all the relationships:
1) Number of games
2) Number of Grail wins
3) Average score (games/Grail wins)
4) Prize-winning places
5) Best result.
This way, it will be possible to see the relationship of skill within one version (because there will be a separate table for each stage), as well as overall.
And individual tournaments can easily fit into the overall concept of this tournament, because it implies 10 separate stages (i.e., possibly 10 separate tournaments).
