Gray haired local here. Made a similar mistake several years ago on my first attempt of the Mythic Wall and aimed for the good belay off of the ground way far left. Ended up committing and climbing 4 pitches in the neighborhood of your route. Called it "Four-long and Forlorn". Amazing how much choss there is in on that wall considering the relative quality of the Mythic Wall Route.
Cheers Fellows!
