Dont think that is correct.
CNF points are points 5 letter non-pronounceable (like all of the FAA waypoints are
) only used for the internal coding of the FMS for coded procedures.
These waypoints and that nomenclature are establish for coding purposes only such as the centerpoint of a turn. Typically the first 2 letters are the last 2 of the airport, in this case, NGXXX.
They are not represented on charts, and waypoints are not in parenthesis.
