Hi Jager,
Since you are still defending your made-up ACM term, let me address this as diplomatically as I can. Please try not to get defensive about it. I'm not trying to be a jerk or make you look bad. I'm trying to clear up the misunderstanding here and explain why it happened (which is not entirely what you think).
Based on your earlier descriptions, it sounds like you nose down (apply neg G's) and then do a barrel roll. If so, that is all you need to say. The rest is unnecessary and misleading fluff. Here's why:
I did a barrel roll (or canopy roll, both would appear to be accurate descriptions of the basic maneuver performed), and there was a large amount of displacement.
After a quick look around, there is no specific name for such a maneuver in which the original heading is maintained.
Yes there are terms for this, and you just used them. They are "barrel roll" or "canopy roll", which are displacement rolls in which the original heading is maintained.
Thus the term "high displacement barrel roll" would be accurate if positive g's were being pulled.
No, this is a made-up term and does not exist. You are doing a "barrel roll". If you want to say it is a barrel roll with a large amount of vertical or horizontal displacement, then just say that. The problem with using the term "high displacement" is that a barrel roll by it's very nature is a displacement roll and "high" can mean multiple things (just in this context alone), so it comes off as confusing and unnecessary fluff, not an accurate ACM term.
Now, the definition of inverted is "put upside down or in the opposite position, order, or arrangement.". And what I did was the mirror image of a high displacement barrel roll, only with negative g's. Thus the term "inverted" is, if not perfectly fitting, then at least quite close.
The word "inverted" is the wrong term, even if you think it's close. But it wasn't the only problem with the term you made up.
I'm curious, though, about your claim that this is a completely negative-G maneuver (for which you were using the term inverted). Are you doing a barrel roll while canopy outward during the entire roll? If so, I'd love to see a film of this. Although, I don't see any benefit of doing it negative-G, because the con is passing inside your roll and you (by being canopy out) would be losing sight of the con for most of the maneuver.
What I think you are really describing is pushing negative-G's (nosing down) and
then doing a barrel roll. These are two separate simple maneuvers put together. And it is a good "move". In fact, if you had just said: "I just nose down into the merge and then do a wide barrel roll to avoid the HO" it would have been a very good post IMO.
There was no ACM pre-established ACM term to describe what I was trying to describe.
Yes, I think there was. You just didn't know it. So, you felt obliged to make something up. I think you can see now why that is not a good idea on the training forum.
That is a fact. And because I said "inverted" instead of "negative-g", Feind got upset.
The implication was that I was trying to sound more knowledgeable than I am, and that I was intentionally just making up terms willy nilly. That is unnecessary, and frankly not becoming of a trainer.
It isn't "fact" if you are making it up. You did make up a term that had inaccuracies.
You have to remember that this is a real pet peeve of trainers, when people put false or misleading information on the training forum. It IS their job to refute that kind of "information" on the Training Forum. It also is in their best interest to discourage people from posting things they have to refute or correct. Unfortunately, you were on the wrong side of things this time.
I'm not a trainer, but I think what I said was accurate. However, if I posted something incorrect here, I hope someone will correct me, both for my benefit, and more importantly for the benefit of those reading it who may not know better.
For the record, Jager is right about this: a slight nose down followed by a barrel roll can effectively avoid a HO shot.
