As the length of the observation period gets longer (e.g., from a month to a year), more people will buy a brand, their average purchase frequency will rise, the percent who are repeat buyers will increase, and rates of 100 percent loyalty will fall. Loyalty, therefore, has to be defined with reference to the observation period.
