Thank you for your suggestion. We researched more literature on the subject and adopted a more moderate perspective for assessing normality (|Sk|>2-3, |Ku|>7-10 and |KuMult|>10). As you mention, with the elimination of the extreme values, the skewness and kurtosis values improved significantly, approaching the range -1 to 1.
Table 2 and the paragraph after it is a repetition of Figure 1 and Table 1, could be cut.
