How can accuracy in results be improved with a limited number of screened tasters?

Improving accuracy in tasting results can effectively be achieved through repetition. When tasters are given multiple opportunities to conduct the same assessment, any potential biases or variability in their responses can be averaged out over time. This method allows for a more reliable measurement of the shared sensory attributes being evaluated. Repeating tastings gives tasters a chance to refine their sensory perceptions and develop greater consistency in their judgments.

While increasing the number of tasters could potentially offer a broader range of opinions, it is not a viable option in this scenario due to the limitations mentioned. Using more randomization could enhance the robustness of the results but may not directly address the accuracy of individual responses. Relaxing screening criteria could lead to the inclusion of individuals who might not be well-suited for tasting, potentially compromising the integrity of the results. Therefore, repetition serves as a direct method to enhance result accuracy within the constraints of a limited tasting panel.
