Yeah, I did mention this as well in another(?) thread asking for advice on drop weight machines that after calibrating a drop weight machine, when stringing it is best for consistent tension to have the gripper as close as possible to the position when calibration was done. This is especially true for drop weight machines which employ this type of gripping mechanism, like the superstringer. The size/weight of the gripper will also affect how much difference there will be. In your pictures, I think the gripper you have seems to be of the smaller/lighter variant, so the effect will be less compared to the bigger/heavier versions. IMHO, in my own case, the deviation can become too big to ignore, especially if the ending position of the gripper varies too much throughout the whole stringing process.
