When I said the Ti had lower resistance, I really should have said it differently. What I meant was in relation to the anodized parts it adds a lot of surface area that I thought should lower the voltage over hanging wires or aluminum racks when the racking surface area is accounted for.

With small loads in the 3 amp range, the peak voltage in our setup may be only be in the 11-13V area @ 8amps CD (rack not factored in). With loads in the ~15 amp range (again @ 8 amps CD), I see it reach 15V to high as 17V.

It just seems like there would be some way to factor the rack in, like adding a consistent amount for a certain rack SA to compensate. I don't know how to factor or calculate that though, and since there hasn't been any known end problems and I don't have much free time there hasn't been much incentive to experiment and learn more about it. I have thought about doing some very small loads to try and compare, but since my power supply resolution is not that small there would probably be a lot of built in error which would make tests inconclusive.

Do you think that calculating an empty racks surface area, and applying a given current that the voltage it takes would provide any usefulness in how much current is "wasted"? Or are saying that it would depend on the work versus rack area?
