To test the applicability of Polarized Projective Mapping (PPM) to dry South African Chenin Blanc wines, one Projective Mapping (PM) and four PPM experiments were performed using expert judges. PM was used to create an initial product map for comparison with PPM results and to assist in the selection of the three poles. For the purposes of method validation 17 wines were analysed in this set of experiments. As the use of poles as stable references between evaluations allowed, the PPM results from all four PPM experiments were combined in a single statistical analysis. This gave a single figure which compared samples from all evaluations in a “Global MFA”. In this experiment repetitions, blind duplicates, explained variance, confidence ellipses, and grouping trends were used to establish the consistency of the results. All of these parameters indicated good reliability of the results. PPM consistently separated wooded and unwooded wines with acceptable percentage of explained variance and correct groupings of blind duplicates. The overall groupings were also consistent with those found in PM.

为了测试偏振投影映射（PPM）在干燥南非Chenin Blanc葡萄酒中的适用性，使用专家判断进行了一个投影映射（PM）和四个PPM实验。PM用于创建初始产品图，以与PPM结果进行比较并帮助选择三个极点。为了方法验证的目的，在这组实验中分析了17种葡萄酒。由于允许在评估之间使用极点作为稳定参考，因此将所有四个PPM实验的PPM结果合并到一个统计分析中。这给出了一个单一的图，该图在“全球MFA”中比较了所有评估的样本。在该实验中，重复，盲法重复，解释方差，置信椭圆和分组趋势用于确定结果的一致性。所有这些参数表明结果具有良好的可靠性。PPM始终将木酒和非木酒分开，并具有可接受的解释差异百分比和盲目重复的正确分组。总体分组也与PM中的分组一致。
