Ohms per foot is a meaningless number. It is measured by a small DC voltage when you use an ohmmeter.
Ohms per foot is used by plug wire manufacturers to try to get you to believe that their wire is better than someone else's.
The power for the spark event is more like AC and it flows over the surface of the core, kind of a cylinder flow.
It would take pretty specialized equipment to measure the power flow in a real spark situation.
Year ago, Circle Track magazine did a plug wire test and the results for new carbon conductor wires (the stock ones most of us consider crap) were indistinguishable from any of the other wires. I seem to remember that all the hp numbers were within the testing error, including solid conductor wires.
Wires add value when they:
1. Last a long time
2. Withstand reasonable handling and operating abuse
3. Control RFI so your other electronics aren't affected.

Good points and they are why the fuel teems use them with Hundreds of runs on a set of wire with 44Mag with no problems on top dragsters and I believe over 100 runs on a top fuel car using Firecore50.Schumacher tested the wire in his own facility as has been seen on youtube including in a pressure chamber.
