Which statement is NOT true regarding the rules for changing a competitive set?

The statement that a single hotel may be added to a competitive set at any time is not true. In the context of competitive set rules, changes typically adhere to certain conditions to maintain consistency and relevance. Specifically, adding a single hotel often comes with restrictions regarding the age of the property or its connection to existing competitors in the set.

For example, the requirement for a hotel to be operational for a certain period before being added to the competitive set helps ensure that it has established a stable market position and operational history. This is crucial for maintaining the integrity and comparability of the competitive analysis. Thus, the notion of unrestricted addition of a single hotel does not align with the established guidelines and principles governing competitive sets in the hotel industry.

The other statements relate to the structured approach to modifying competitive sets, emphasizing the need for strategic reasoning behind adjustments, such as including hotels from different chains to ensure varied competitive analysis or the necessity of making dual changes (adding and dropping) for balance.
