I doubt if any even cares, but I had an epiphany!
looking at the data sheet for the lock nut
It states an axial static loading, (but not specified as recomended nor maximum) of 50 KNextons (11,240 lbf)
using the known area of the threaded section, the Kpsi tension loading caused my tighten the nut is easily found
Then with that Kpsi, the torque can be calculated with the equation I used above.
I was surprised! Not wanting to give this as a recomendation so I will let oneone interested find for theirself, But I will say, use the nut ONCE!
