With NWS off, there's not going to be any additional steering capability based on nosewheel load, so that part doesn't matter.
You are going to obviously slightly change the downforce on the mainwheels as a result of the stick position, but it's not likely to be big percentage change, and given the fact that you aren't testing on a representatively wet runway, so the main wheel friction/cornering powers are all wrong anyway....
Our procedure is usually to keep the stick somewhat neutral, but I suspect that the variability of the test in terms of, for example, pilot reaction time will swamp any stick position effects.
