Chum has always had an attraction rating, however it hasn't been displayed until now because of the recent confusion.
Many people became frustrated that chum prices and chum loss %'s changed -
without understanding that for example, Cayenne Chum (9% Attraction Rating) catches 4% more fish than Steak Chum (which has a 5% Attraction Rating).
We feel that users will have to rethink old strategies with this new information becoming public.
A 9% Attraction Rating means you'll increase your chances of making any catch by 9%, and lowering your chances of not catching anything by 9%.
Please do not contact us about your catches/steals being wrong. Instead read: The Law of Averages.
