Scott, I can't think of examples of PP changes, but I am thinking of the format in WITW. (new code change format) where I leave them in 1st position. It might be interesting to do a pre post test on this and see for yourself what you discover. (In fact, thanks for the suggestion :-) Although I would still come back to 1st to finish. As to other indicators. Look for any observable Px stuff. Success means physiology is more like high performance otherwise, redo. Px=Physiology Thing like: breathing, posture, micromuscle movement, head tilt, balance/symmetry, voice tone, etc.. Hope you get the idea. May be an elementary answer, but they say that mastery is the art of mastering the basics... (Whoever they are ;-) Calibration is as basic as you get. Hope this helps, Todd PS did you mean submodality changes in other perceptual positions? Or some kind of actual changes in position? Or...?
