Nicely done. Regarding the guidance back to landing site, how precise of a window are you hitting with the boostback burn? Is it like shooting a basketball into a normal hoop, or one 20 times the size of the ball, or a super-tight one? I guess what I'm trying to get a sense of, without asking you to violate ITAR 😅, is whether the grid fins and body lift can do a ton of work to bring an errant rocket back over the landing pad. Or if it's the case that a moment of imprecision near apo makes the on-target landing impossible.
The boost back burn is actively guiding but it just gets the rocket close then the majority of precision is from the grid fins and the final landing burn. With this design you can actually have fairly good cross ranging capabilities. If you check out my playlist with KOS KSP landings I have a recently uploaded profile view of the landing which might help. You can also see the progression of the design.
