Great improvements! I do find it interesting that jpeg now needs a fair number of post-drt diodes. Is that from not following guides or jumpers?

Yes, I believe that's the case. Post-GRT repair was able to fix the violations only with the jumpers, but in DRT it wasn't enough, probably by not following the guides.
