Oh, yes you're right...hmmm. Unsure what to do about that, I'd love a neat graphical solution. Wasn't quite sure how to represent repeating units without just duplicating subdiagrams!
Many thanks! I have residuals going from before to after the MHA block, and from before to after MLP+FFNN. Should I have others in other places?
edit: Those links are super!
Many thanks!
