IMO, the patent is about diagnostics, analysis and follow on treatment related to testing. Agree it seems likely other treatments (ex. A xxx) might follow a specified variant sequence and defined treatment protocol.
IMO, this is a variation of ..."take 2 of these and call me in a week." . It's about being more precise with subject analysis and corresponding S1R treatments.
They are zeroing in on custom medicine for each subject by applying unspecified analysis and corresponding treatment, but all w/in the S1R MOA envelope.
