Remember that dividing revenue between routes (or more strictly, service codes) was just what the famous BR ORCATS system was designed for. Train-specific APEX tickets obviously didn't need to be divided up.
With both East Coast and West Coast offering a broadly two-hourly service, leaving Glasgow on alternate hours and taking about the same time (i.e. not 'overtaken') it was fairly obvious that Glasgow-London revenue would get split about 50/50 in logic terms, regardless of whether a larger proportion actually travelled on the 'traditional' croute.
