Playing around with cfg technique, I'm finding that turning off guidance at the 40% mark causes requested fine details to not appear in the final image. This sorta implies that switching cfg midway and/or switching prompt vectors might be interesting from a prompting standpoint, but it kinda kills it as a performance optimization.
