Now and then a pc does not understand that he is supposed to be erasing a PICTURE and only goes far enough to erase the somatic. Auditor says, “Is it erasing?” Pc can’t feel somatic so he says, “It’s gone.” Auditor puzzled by no F/N but buys it.
What you want to know as an auditor is “Is the picture erasing?” You can use that line to check, but not habitually.
Erasure depends in some measure on the pc getting to the BEGINNING of the incident. Sometimes the pc keeps starting a bit late in the incident and so does NOT get an erasure.
If you assess an item like “Dizziness after an operation” and try to run it the pc will bog utterly as the whole operation precedes the somatic called for and not only won’t erase but also won’t show as a picture.
Trying to run a somatic like “my mother’s hitting me” is a narrative incident not a somatic. It won’t erase because you can’t go earlier on the somatic as it’s not named. There’s probably a whole chain on “a stinging face” and chains are connected by somatic, not narrative or the same people or incident type. FEELING makes the chain. Only chains of feelings (pains, sensations, misemotions, etc) uniformly go down to a basic that will erase.
