Nah it's correlated, if you're having fun you're more likely to be relaxed, and if you're relaxed, you're less likely to make mistakes, and thus you end up playing better.
Yeah thats true they lost twice, but one, only a few teams have made it two or more international lan finals, and two, they were actually put under significant pressure for once due to jinggg leaving.
See prx operates by not putting pressure on themselves with a kind of go next attitude, if they lose. But you can't just go next when Jinggg is leaving.
