I'm gonna go ahead and state my theory that Black Sabbath's Arrow is much weaker than other Arrows due to the enegy it used to power fat-ass Polpo's Stand (since Black Sabbath, as a Stand, can't operate without the Arrow, since it's part of its power and presumably absorbed the Arrow Diavolo gave to and struck him with). Therefore, this means that it possesses only a fraction of the regular spiritual energy committed to a person by a regular Arrow.

So, when it struck Giorno's Gold Experience, it didn't turn it Requiem, but it IS the reason the Stand later developed the ability of transformation during the 'Baby Face'. And, presumably, after returning to Morioh, Kouichi's Echoes either reached Act 4 (since it still has developmental potential 'B'), or just developed another ability (maybe stronger sound applications, or a greater-ranged 'FREEZE'?).
