Peak to Valley Resolution

I am trying to determine if it is possible to calculate peak-to-valley resolution between two partly-resolved peaks.  I do not see any calculations that would immediately allow for this to be calculated, since I am not sure if it is possible to use the height of a valley in a calculation since the valley itself is not labeled as a peak.Here is an excerpt from USP General Chapter <1053> Capillary Electrophoresis:
When appropriate, the resolution (Rs) may also be calculated by measuring the height of the valley (Hv) between two partly resolved peaks in a standard preparation, the height of the smaller peak (Hp), and calculating the peak-to-valley ratio:

p/v = Hp/Hv
Does anyone have any ideas?

    We found the answer.  Empower has the "Start p/v" and "End p/v" fields that should be what we need.
