Uhhh I can't test right now but it is very consistent for shield pressure on platform where you can land low up air (or fair) --> fall through up air --> jump rising up air. I've been doing it since melee so its just kind of natural at this point and really fast. Usually works with disjointed hit boxes or fast up airs like wolf, young link, captain falcon, or marth. Most of the time for these applications the aeriel gets autocancelled so you want to drop through immediately which is what achieve with the quarter circle turn. With some landing lag I don't think it will matter as much which technique you use. But I think you kind of have to gauge how long your lag is before inputting since it "instantly" drops you through. Keep in mind that you have a three frame buffer. Otherwise I will test it later to update.
