So, another way of saying this is that data derived from league play doesn't translate (as well) to tournament cross-league play when used as a predictive indicator.
Which to me makes sense, the less data available the less accurate the prediction.
Also, League and tournament rules are very different. As an example in league, you can only sub X number of times + once you're subbed off players are typically out for the half/game. In tournaments you can sub like crazy. Another example is in league you can't put together super teams with players from multiple clubs. In tournaments you can do this. Surf Cup won't let true super teams play in the top flight but 1-2 top players might be guesting with top teams which wouldn't happen in league.
Keep in mind that the ratings data tied to most of these teams (if you're referring to SR data) is already a combination of league and tournament data. If you are instead referring to league standings alone not holding up in tournament standings - that's a defensible position, but I'm not sure it's necessarily accurate. And even though play seems to have been a bit closer to parity in some cases rather than an excessive amount of mismatches that predictions might have implied, the end result is still that the teams picked to win ended up winning their games - at similar percentages as would be expected - even the ones called out here. Perhaps the tournament sub rules do help keep some games closer? I'm not sure why it would, but perhaps it's possible. It seems that the sub rules could advantage or disadvantage any particular team, if other teams/clubs are subject to the same. I thought it would be shorter games that could keep things numerically closer - but it turns out that pool play games are similar length to league games, so there wasn't a difference there.
