...The 90-pin probing system used on more recent cards is NOT lossy with Z approx. 93 ohms.

To be clear, what I mean is the tiny ribbon coax used in the 90-pin system has a characteristic impedance of 93 ohms.? I did not mean to imply that's the impedance at the probe tip.? The input impedance at the probe tip is much higher and is given as a model depending on the pod being used.
