(OP)
I appreciate comments from anyone who has gone through this design guide and its illustrative design example in appendix E (for a steel frame structure) regarding the calculation of the m factors.
Please see attached.
Thank you.

No, as of now, I haven't figured out how they came up with those values.
I ran into the similar problem when I tried to duplicate their "a", "b", and "c" values in Table E-7 (p.146) for W24x68, etc.

On the beam/girder m-factors, the bf/2tf and h/tw values in your calculations are not consistent with the values in the Steel Construction Manual. For a W24x68, bf/2tf = 7.66, and h/tw = 52.0
