Well, the description of this field does highlight the potential biochemical and health benefits that heart-brain magnetic coherence has been found to have, so that aspect of this field might be what our friend was noticing in PF.
Fields aren’t combined wholesale, so it’s not a 1-to-1 equivalent (or “replacement,” as is often asked on here). The way I’ve described it in the past is like making a stew. I might add a carrot (PMHC) to my “stew” (PF, in this case) but the effect of my carrot in that stew is going to be different from eating the whole raw carrot I had started with, and its contribution to the final stew will be different from the whole raw carrot I started with.
