Your thoughts on upgrading Feickert protractor

I have the NG and the pin eyeballs maybe a couple thousandths inch clearance to the sleeve.  Not really sloppy.  
I have a question about procedure though.  The instructions are vague, or I'm missing something.  What I did, and it worked, was to set the overhang at step one while aligning the cantilever to the overhang grid line.  At step 2 I moved the platter so the cantilever was parallel and on the grid line (but stylus was not at an intersection?).  At step 3, without moving the platter, I checked for parallelism at the inner null point.  
Sounds great but is this proper usage?  Thanks.

Slaw,

I don't have to move the platter to align the cantilever at step 2.

The NG instruction for step 2 (outer null point) states emphatically (Bold italics) that the pin no longer needs to be aligned over the pivot point for this step.  Their reasoning is that if the overhang is correct and the inner and outer null points are parallel then all is good.  My interpretation is to adjust the platter until the cantilever is parallel to the grid for step 2 (outer null point), go on to step 3 (inner null point) and, if also parallel, all is good.  I think that’s a valid check, but not sure I’m interpreting the instructions correctly.  The stylus, while on, and parallel to, the line is not at a junction (cross-hair) on the grid like I’m used to seeing on other protractors.  It worked and quite well.  Was it dumb luck though?

if steps 1 & 2 are spot on, moving to step 3, the cantilever will be slightly off 

Feickert suggests that If the cantilever is slightly off at step 3, it is telling you steps 1 and 2 are not spot on. 

Step 3 “check parallelity with lines on the inner null point.  In case 
parallelity doesn’t match (step 2) go back to (step 1) Otherwise planar setup is finished.

Calm down.  Not a setup at all.  Your info conflicted with the instructions and I pointed it out.  It’s a discussion, not a judgement.  With an open mind I had hoped for clarification of your opinion about the nature of tone arms. I thought the Feickert instructions vague.  Still do.  btw my moniker at the vpi forums is not wlutke.
