Sort of.....
I don't think that was it, the one I was thinking of had PPDPW and PPDPWP$. With the prices that tj mentioned, once you take the PPDPW and divide by the cost of the card, some economical choices become obvious.
As people are looking at folding and worry about the cost to get performance (both in electricity and cost to purchase), it reminded me of those two metrics. If our team does go back this direction, we may want to resurrect the concept. We could look at that sites yield numbers and divide by price. That might provide a number that is similar to PPDPWP$.
