Statistically speaking 100 rolls (300 quarts) Is good enough for a 50/50 shot.

Your odds per dollar degrade pretty hard after that. With an additional 100 rolls giving just ~25% more chance.

Personally I don't really spend more than 300 on a banner unless it's someone I want really bad, and there's only <5 of such servants in the game and half of them aren't even 5*.
