The Sharpe Ratio does not capture that difference: It so happens kestneer when it is non-negative, this quantity is also the t-score for the rejection of the hypothesis, “The true regression line has slope less than or equal to 0”.
If the adjustment made for the modified K-Ratio were such that monthly and quarterly data now gave the same or roughly the same values, then I could see how an argument for the adjustment could be made. For an intuitive understanding of the Zephyr K-Ratio, it is enough to know that the more closely the actual cumulative return graph hugs its trend line, the smaller the standard error of the slope will be.
