Hi. The manual re. HTDcPeriod says

Code:
HTDcPeriod(var* Data): var
Hilbert Transform - Dominant Cycle Period, developed by John Ehlers (see links). This function is less accurate than the DominantPeriod function.


without any description of why DominantPeriod is more accurate. They give obviously different results, but what makes DominantPeriod better?

Also, there is no DominantPhase as there is an HTDcPhase, etc. Do these not make sense for DominantPeriod?

Thanks.
