Author (experts) help is needed urgently!!!!

the probe damping factor of the ultrasonic received pulse is calculated on the basis of no of positive half sycles over 25% of the largest one, but; sometimes the negative half cycles are greater than the postive ones even the largest half sycle is negative.
the question is: calculting the damping factor based on the negative no. of half sycles is right or wrong?
