Geoff -- Yes, I would say that my friend's system is at least as resolving as mine is currently, and possibly more so. If I cannot discriminate the presence/absence of the grounding pigtails in his system, I will conclude that Al may have been right when he suggested that what I heard the day I put in the pigtails might be attributable to some other variable.
From your use of "pray tell," I gather that you are going to say that I cannot conclude anything of the sort, because the pigtails may have some effect in my system but not in his, due to differences in equipment, ac power, acoustics, barometric pressure, solar flares, the state of my electrolytes, etc. etc.
Maybe you were implying something else. It's hard to know when you don't finish your thoughts.
