Anyone have any thought on what to use for the following numbers.

Material: CE
Impedance: ZO of the differential trace is 50Ohm and ZOD of each
differential pair traces is 100Ohm.

I built a board using 8 mill traces with a 8 gap between the pair, and
.008 gap between plane to sig and then plane.

Numbers were not what I expected, fabhouse used Polar+fudge factor to
give me the numbers.
