The results obtained using all epochs found in the experimental set with lengths and 2000, instead of only the longest one. At least one representative epoch was found in this experiment for up to length from each record, whereas it was possible to draw more than one epoch in other records (That is why for , but only for , some records were not included in the experiment in that case). Each column refers to records of the same length, as shown in the N row. For all cases , and . In a few cases Acc coincides with Sp or Se due to value rounding and classes imbalance.
