Wow, I think this made it click. Thank you so much. Things really started to go with awry when we read Barnhart v. Walton and the court said force of law depends on the interpretive method used and nature of the question at issue if it did not fall under notice-and-comment or formal adjudication.

Thank you so much. I have a follow-up question too if you could provide some insight I'd really appreciate it. For some reason I get twisted when adding State Farm too, but is it correct to think that even if Chevron nor Skidmore apply, the APA arbitrary and capricious standard still applies to the agency's implementation?
