Yep, there should be some resistance, and it’s significant resistance as we are tightening the rod enough to straighten the neck. So resistance is expected, but if you notice a sudden increase in the resistance, that’s an indication the nut may be out of threads.
So if there was little tension to begin, it sounds like the rod was pretty loose. That would make sense if you didn’t see much change. If so, you will probably have a few more cycles of adjust/check before you get close to where you want it. BTW, I think you are already aware of this, but you can make more than one cycle of adjust/check in a sitting.

Well Mike, I think we may be making progress!! I sat down again tonight, loosened up the strings and gave the rod a 1/8 turn. The resistance was stronger but now I see that it’s supposed to be. I guess the nut was just really loose.
When I re-tuned I was happy to see that the playing was already better. The muting I had experienced before on bar chords was MUCH better but still not quite where I wanted it.
So I de-tuned again, gave it a very cautious and slow 1/8 crank and tried again. Better and I’ll give it a closer look this weekend and post some new measurements and a relief check.
In total, I guess I’ve tightened about 3 1/8 turns, maybe a little over that. I don’t think I’ve gone quite to 1/2 turn but I may have. In any event, I’m interested to see how it’ll play with new strings. Got some new ones I’m gonna put on when we’re done with this.
The saga continues…but there’s light! Thanks!
Mike
