I set it differently game to game. I believe each game has a different level of nudging that should be appropriate. Not every game has the same rule set or layout, not every game should have the same level of tilt strictness either.

PAPA provides a list of recommended game setups for tournaments that frequently mentions tilt tightness, and I think their tilt recommendations are generally great: https://papa.org/learning-center/directors-guide/
