The problem for me isn't the cap itself but bad events "stealing" event slots when your scales aren't maxed everywhere, so you need a very strong dominion or to be turtling to have reliable effects.

It's very rare to have luck 3 everywhere when you are expanding, you often have provinces with luck 0-2, or even worse with your turmoil scale but not luck (or with the misfortune of a neighbour). Then you may get an half of bad events, replacing same number of good ones, and these events can nullify the positive effect of the scale.

Order of course only give bonus where the scale has been developped, but provinces without order don't steal the income bonus of provinces having it.

Tests don't represent that well, as they are usually based on strong dominion + temples everywhere + no expansion.

I think the best way to reevaluate luck scale would be to check provinces by decreasing order of local luck (so you'd get events in provinces with low/negative luck scale only if the total number of events of your lucky provinces didn't have reached the event cap).
