At Bridge Winners they are already are complaining about possible cheating.

In any team game, systematic cheating can readily be made apparent because team scoring means only certain contracts have somewhat predictable payoffs..

Everything else is mostly dependent on field placement; a matter of luck (and skill playing any contract won, or defeating any opponent contract) more than a particular contract itself. Field placement is only determined after the entire field finishes each deal, and therefore unpredictable even to a pre-knowledgeable cheater.

There are a relative few of those somewhat predictable contracts, and they are rankable in importance in a competition. Therefore we can simply follow their results from most, to least, important, and look for any pre-knowledge pattern.

This process seems to me rather simple once you see it. It is applied logic in action, with no statistical assistance needed.

All this is a bit more complicated for pairs. Therefore I will leave that for later. At this time, the important competitions seem to me to be usually teams.
