Only if desired torque is 30_35 lbs . The object is to line up the tube /nut with the nut tight enough but not too tight . When you get past , 80- 85 you are really straining the aluminum threads . From 35 to the next hole is normally within the range . If you don't need to align the nut go around 50 and be happy .Constructor got it. Torque to desired ft/lbs, then tighten to the next hole.
I'm not under any mistaken idea that there is any "perfect" barrel assembly method. I just do what I do that works
Were I building some target rifle that I had to guarantee met some accuracy standard, I'd probably do things differently.
I haven't built (assembled?) hundreds of AR's. Each of them (probably 15, give or take) has been a learning experience that I enjoyed immensely.....and hope to "assemble" many more! LOL!
