I get asked that by one T and have struggled a LOT with it; for a long time it irritated me, made me upset, confused things and seemed such a pointless exercise and such a complete waste of time both for me and for T. I'm slowly, very slowly, starting to see the value in it. Although thankfully it isn't as detailed as the 7 part analysis you mentioned; more a what are you feeling and where within your body. I'm starting to see that doing it now isn't as irritating or confusing or upsetting ... but more, gradually starting to be calming. Taking my focus away from the strong feelings that I can't cope with and helping somehow to become more relaxed without actually needing to "do" anything. It's also helping me start to take more ownership of my body (something I really don't know if i want to do?? and yet maybe it is a good thing?). There was an article or blog or something a few days ago on PC about just this and saying how it is being used more; now to find it again! (it's there somewhere but where i don't know)
