No, you're completely confusing
two separate techniques.
A Recoil Special results in you facing the same direction you started, and is probably the video example you're referring to.
A B-Reversal is a
component of a Recoil Special, but it is not, in itself, a Recoil Special. They are
distinct. You're making arbitrary definitions about when and how each can be used that
do not exist.
If you just do a B-Reversal, you get your momentum and your direction reversed. You end up facing backwards and moving the opposite direction you were. If you do a turnaround B immediately followed by a B-Reversal, you end up facing the original direction having gained reverse momentum. This is commonly known as a Recoil Special.
You're lumping them together as one technique, and proclaiming quite inaccurately that when you perform this amalgam technique during ascent, a Recoil Special occurs, and when you perform it during descent, a B-Reversal occurs. You could not be further from the truth. You can do
both of them in ascent AND descent. You have a vast misunderstanding of not only what these techniques really are but how they interact with each other, as well.
I can't emphasize
this enough: You are incorrect. I am not speaking hotheadedly, I am not speaking out of emotion, I am not speaking out of anger, or spite, or insult, or hurt. I am speaking out of
knowledge.
You're not listening to me! You do not fully understand the mechanics involved, and you aren't listening to my
thorough explanations detailing what is really happening. The results of identical inputs AREN'T different, they're the same. The results of DIFFERENT inputs are different, yes. When you choose to perform only Recoil Specials during ascent and only B-Reversals during descent, it does absolutely nothing to prove a correlation between those particular moves and the direction of vertical movement.
Both can be performed during ascent, and both can be performed during descent.
How can you possibly claim the inputs are even the same in these cases? They're the exact opposite. In your "ascent" case, that is really a Recoil Special, you slam right on the Control Stick. In your "descent" case, which is a pure B-Reversal alone, you slam left on the Control Stick. Those aren't identical inputs, they're opposite inputs. The reason the Recoil Special occurs is because you are unknowingly initiating a turnaround B because the space between your release of the Control Stick to DI backwards and your input of a neutral B is short enough for the game to interpret a turnaround B. The length of that gap determines whether or not a turnaround B occurs, and you aren't allowing a large enough gap to NOT perform one. You unknowingly perform a turnaround B, then you B-Reversal it to the right, facing you back forwards again.
The reason a plain B-Reversal occurs in the second case is simply because.. that's how a B-Reversal works. You initiate, then you slam backwards on the Control Stick. Simple.
Any correlation between these two
distinct techniques and ascent/descent stems entirely from a lack of understand on your part and an inability to perform these techniques correctly in all situations. You perceived correlations are merely reflections of when you, personally, succeed and fail at inputting these commands. The differences you proclaim DO NOT exist, however. I honestly don't know how much more clear I can be.
Believe me when I tell you that I know more about B-Reversals than either of you. I have put large amounts of my own time into researching them for my own benefit and so that I am able to make informed posts regarding them to others in this community. You are misinterpreting what is going on, and you are being thoroughly stubborn about considering that fact.
Your second paragraph in that last post perfectly demonstrates exactly
why you need to stop being so stubborn and start listening to what others have to tell you. If you think that that is how a B-Reversal works, then you DO NOT understand B-Reversals. If you think that a B-Reversal alone could EVER leave you facing the same direction you were, then you DO NOT understand B-Reversals AT ALL.
PLEASE stop being stubborn and take a moment to listen to what others have to say.
Edit: As a corollary to Damax's post below this one, I'll offer you links to the original threads containing in-depth videos for both Recoil Specials (called wavebouncing at the time) and B-Reversals. If you familiarize yourself with the differences between them, and simply watch all of the videos involved, you'll probably start to see that your distinctions between "ascent" and "descent" of your fictional amalgam technique are, in fact, distinctions between two different techniques. While they are related, they are definitively distinct, and you need to understand this.
Additionally, while Zero9teen speaks only in terms of doing Recoil Specials through B-Sticking, it is just as possible to do it without, and you are already doing it quite a bit, mistaking it for something else, dubbing it your "ascent" case.
Here are the links:
B-Reversal Original Investigation Thread, by Jewdo
Recoil Specials Early Investigation Thread, by Zero9teen
I'd link to Panda's related thread, too but.. frankly these two are more helpful right now. You need to understand the difference between what you mistakenly believe to be different effects of the same move. These two threads have several videos that can show you quite well what that difference is. In particular, Jewdo's second video should give you a very clear understanding of the fact that a B-Reversal will ALWAYS reverse the direction you face.
Always..
