No computer assistance besides using alg.cubing.net to check the solution.

Most of the solve was done with the yellow-blue-orange corner block at the DBL location. This was to make it easier for me to track which face was which, but the downside is that some of the steps look like black magic because that's not the actual orientation I did the moves from.

The rby/ryg blocks were super lucky. There was already a free red-blue square; I saw that the F R U R' U' F2 L' U' L U F alg would cause the edge pieces for the red-blue-yellow corner to get connected immediately, and just doing an R2 there would form the red-blue-yellow block. However, this leads to parity (two 3-cycles and a 2-cycle of wings), and I think parity here is linked to the number of outer layer quarter turns. So do a few setup moves to bring the two squares to adjacent positions (to be paired with R or R'), and what do you know, there are two other free squares that also get paired up when I do that. So, that's how I got two blocks in only 17 moves.

The EG1 case is literally the only non-PBL EG1 case I know, and I don't even use it in speedsolves because I don't remember which angle it's supposed to be used from. Good thing it showed up, huh?
