I've been following this post for awhile now, and you seem quite enamored with this Delta meditation. But I haven't found any place where you explain what it is. Is it a certain program from a book? or tapes? or your tai chi instructor?
As for measuring your lifting gains, it really is a good idea of recording arm, chest, thigh measurements every now and again, just to note your progress, and know that you are actually achieving something concrete, instead of the more subjective, "Is My Bicep a Nice Pillow Test?" Before and after pictures are also a good idea.
Now, paraliminals. I've been using them inconsistantly for about a year, but regretfully I have not noticed a tremendous difference. There very well could be a difference, but I just have not noticed it to any great extent. I still listen to them as I fall asleep each night, such that now, I believe I've conditioned myself to get at least drowsy whenever I listen to them. Even 10 minute supercharger leaves me drowsy, but relaxed. Obviously, this is not what 10 minute supercharger should be doing. 
Though deep relaxation does feel like an hour worth of sleep. After only an hour of sleep, I usually feel more tired than when I started. Other people seem to get a lot out of these tapes, and I know the principles of NLP work, so these tapes are definitely doing something, I'm just not sure what. There probably is a fair amount of resistance in my conscious mind, for I always am much to doubting and critical. Would that really change things though? Paraliminals are supposed to bypass the conscious mind, no?
