If you really want to get technical, you'd have to test all other variables (decay, impulse, distortion, phase, insertion depth changes, etc; there may be more too) independantly. Some of these variables probably won't be affected (phase), others might. Don't assume anything though. If there is no change, you must show that. If there is change, then we get weird... Either show it'll have very little audible difference, or show how it's positive in some way (much harder to do without subjective interpretation)... That second statement scares me a bit though for two reasons. You assume that scientific observation proves something (please look more into this thought)... And you're trying to imply that you'll formulate an opinion to fit the data rather than the data formulating an opinion.
Your argument begins to fall short as you state that in order to reach this optimal neutrality, you tend to have to add a specific amount of resistance (too much and stuff may be altered too far; negative effects), but also do other things as well (change tips, insertion depth, etc.). It's no longer an independent change causing the positive (more neutral, according to you) outcome.
