Beyond zero faults, such as precise product descriptions, RP's accuracy is based on the principles of honesty and directness. RP believes that data should be accurate enough for the purposes for which it is intended.
Data gathered as close to the action location as possible increases the likelihood of precision being attained. Even if a piece of information has many uses, it should only be recorded once.
In order to determine the value of data, it is necessary to compare it to the costs and effort involved in obtaining it. The data's inherent limitations should be clear in situations when accuracy must be sacrificed.
