Yes, the ELP's are not to be combined as I understand it.
I actually made it up to ELP 14 at one point and then as stated elsewhere Stephen recommended I retake the ELP 1-9, so that is more the norm than the exception it seems. Specific instructions for the ELP remedies are on page 152 of Heal Thyself.
I will ask Stephen for clarification, but it seems to have to do with the stabilization issue he talked about in one of our phone conversations.
