Cycle Parameters Explained The following chart summarizes all relevant parameters related to a "perfect" sinewave cyle:   What is Frequency? Frequency is the number of times a specified event occurs within a specified time interval. Example:5 cycles in 1 second= 5 Hz 1 cycle in 16 days = 0.0625 cycles/day = 723 nHz     What is Strength? Strength is the relative amplitude of a given cycle per time interval. (“amplitude per bar”). Example: A = 213 , d = 16, s = 13.2 per d Read more on Cycle Strength in how to "Rank" cycles here .     What is Bartels Score? The Bartels score provides a direct measure of the likelihood that a given cycle is genuine and not random. It measures the stability of the amplitude and phase of each cycle. Formula: B score %= (1-Bartels Value)*100 Range: 0 % : cycle influenced by random events, not significant 100 %: cycle is significant / genuine Read more on how to validate cycles with the Bartels score here
