Increasing precision can lead to an increase in the required sample size, which can be time-consuming and costly. Additionally, as the estimate becomes more precise, the confidence interval becomes narrower, which can lead to a reduction in confidence with respect to the accuracy of the estimate. Therefore, there may be cases where increasing precision is not necessary or desirable.
