A rigorous optimization over all parameters of Method V: event-related durations W1, W2, anticipated block width (BlockSize), and the offset (β).

All possible combinations of parameters (46,376 iterations) have been investigated and sorted in descending order according to their overall accuracy. The data used in this training phase was heart sounds measured at apex for all subjects with mean PAp ≥ 25 mmHg. The overall accuracy is the average value of SE and +P.
