fahad It is the opposite of Z formula in the numerator and also replace mean with minum acceptable level of return denoted as RL.
bobert It isn't the opposite of the z-formula.

z-value = (X-mean) / std dev.

SFRatio = (Rp-RL) / std dev.

Both formulas look to get an answer that is relative to standard deviation units. Therefore on a normal distribution, you use the SFRatio as a z-value to determine the F(X)
