I am not completely clear on your question. Can you be more specific?
I did review the attached file, and can offer some advice on the results. The %GRR = 80% and the ndc = 1.05 both indicate that this gage is unacceptable for use in process control (SPC) or for use in any type of statistical evaluation such as a DOE.
There may be several explanations for this. The first question that must be answered before going any further is: Is the part variation representative of the actual process variation? If it is not representative, you must repeat the study using parts that exhibit the same variation as the process.
If the part variation is representative of the process variation, you then look at the components of variation. The high %EV = 80% tells you that the equipment itself is a likely place to begin looking.
Check the validity of the 10.010 measurement made by Appraiser A, Part 1, Trial 2. Even changed to 10.0001, the equipment does not have sufficient resolution to "see" process variation. This gives you the low ndc value. If the parts are representative of the actual process variation, you will need to invest in a gage with greater resolution.
Before you do this, what are you using the gage for? If you are looking at SPC, do you have an economic case for it. That is, will the benefit of SPC justify the new gage? Are you using the gage for inspection to tolerance? If you are, then calculate the P/T ratio for the gage. This may be more acceptable than the %GRR.
