Well today I re-served my nock point 1/8th of an inch from its previous location .This was due to my arrows hitting 1" inch below my intended target spot. So I was wondering if there are any other anal tuners here who do micro tuning to there set up.    

"Micro Anal Tuning"? Isn't that for wheelie bows?    

Tell ya the truth... If my nock point is about 1/8" too low my shots go all over the place.

Concern about nock point being off 1/8th" isn't anal. 1/16th?...maybe, although I know shooters whose form is good enough they could tell. (definitely not mine!) Heck, I can get that much variance in the measurement from how much downward pressure I exert when I clamp the bow square on the string.  If you use the narrow bar type like (Potawatomi) it's not as simple as it sounds when you use a thick rest like seal skin.  I split a short length of arrow shaft length wise and taped it to the bottom of the square to make the arrow/shelf contact more repeatable.  Maybe that makes me anal too.....Heh I resemble that remark!

An eighth is a lot when it comes to nock height.

It sure is alot.  I twist mine before setting it solid about a 1/16" or less at a time.

I had it set up so above the nock would shoot my 125gr and below the nock would shoot my 160gr.
