I finally nailed down the right brace height and nock point. I installed my two string nocks tonight. I had to take the string off and when I put it back on it had moved slightly. For the life of me I can't seem to get the nock point back to 5/8. It seems to stay slightly below that no matter which end I twist or untwist. I could be crazy here but it seems if I twist the top or untwist the bottom the nock point should move up. Is that wrong?
Zane, use a tied on nock point and move it by turning it up and down the serving like a nut on a screw. If you twist/untwist your string you will be changing your brace height.

No matter which end you twist or untwist, the twists will quickly equalize between the top and bottom when you string the bow, so the nock point won't change much, if any. Once you put on a few string nocks, you'll get quick enough at it that you can cut one off and replace it in a few minutes. I use nocks both above and below the arrow, and often find that I'm not happy with the spacing or location of one or the other after I put a new one on and cinch it down. I just cut it off and replace it. That's why I don't put glue on them: because I know they will eventually have to be replaced, and the little extra life I get out of gluing the knot isn't worth the extra hassle of cutting off a glued on nock.
Mine don't move an iota when I twist up or down. The only way to move a nocking point is by physically moving it. That to me is one of the more interesting quirks of archery. Kind of a counter intuitive kind of thing.
When you hear shooters talking about "twisting their nock points up or down the string", they are talking about screwing a movable nock point up or down the string - not twisting the string itself.
I like tied on nock points as they are easier on my shooting glove and I generally tie them so they can be moved up and down, but you can also move the crimp-on points if you spread them just slightly and then wind them up or down. Then re-crimp them. They just aren't all that expensive so I usually just replace them if I want to move the nock point.
Thanks guys. These were the first non-adjustable nocks I've tied as I found the adjustable ones moved around too much when I didn't want them to. I found out tonight these are just "more difficult to adjust adjustable knocks" :) . I got them to move it just took more work.
I have to say it still doesn't make sense to me how you can twist one end of the string and it doesn't seem to move the stationary nocks in relation the the shelf. Oh well.
