Most of the spinners think that demon sonic is sonic normal 34-23 ~> pass rev 24-12. But demon sonic have 1.5 rotation. So how must breakdown look like? If this is only sonic and pass rev hybrid, i don't know how to breakdown this in formal type of breakdown. Sonic 34-23 have only 0.5 rotation. So pass must have 1.0 rotation? How it can be?

I have better breakdown of demon sonic:
Sonic normal 34-23 [p][s 0.5] ~ charge normal 24 [s 0.25] ~ pass rev 24-12 [c][s0,5] ~ charge normal 12 [s 0.25]
This breakdown show, that demon sonic have 1.5 rotation. Another variant of breakdown:
Sonic normal 34-23 [p][ s 0.5] ~ twisted sonic 24-12 [c][s 1.0]
This breakdown is right to, but first breakdown show more and i can cleary understand what is this.

0.5 + 0.25 + 1.0 + 0.25 = 2.0 rotations.

I think:

sonic normal 34-23 ~> pass rev 24-12
and
Sonic normal 34-23 [p][ s 0.5] ~ twisted sonic 24-12 [c][s 1.0]

are both acceptable (but not the quoted one).

oops, i made mistake, pass have 0.5 rotation, not 1.0, i already modified my first post.

And what is the difference beetwen
sonic normal 34-23 ~> pass rev 24-12
and
sonic normal 34-23 ~> pass rev 24-12
:D

Whoops, I was supposed to copy the other one....

Edit: Fixed

I've been thinking about Demon's Sonic lately as this:

Sonic 34-23 [p][s 0.5] ~ Passaround 23-12 [s 0.5] ~ Charge 12 [s 0.5][c]

with the introduction of interrupted notation, it is possible that 2 persons who previously thought they were doing the same trick are in fact not doing EXACTLY the same thing.

This, in some sense, constitutes what we call the "style" of the spinner. Two spinners may execute the same combo when written in a standard breakdown (breakdown without interruption notation) but when you look at their videos, it's really different. This is because they're not doing the tricks exactly the same way.

With the new notion of interruption, you can now differentiate those two combos in the breakdown using the advanced notation.

In this sense, old hybrid tricks could be executed slightly differently, which result in different breakdown for them.

Which one you're actually doing reflects in your "style" of spinning.

edit: I also see no interest in defining only ONE exact breakdown for each hybrid trick since we're trying to get rid of them anyway.

If sonic have 0.5 rotation, passaround must start in 24, not in 23. When i'm doing demon sonic i don't do any pushes after sonic, but passaround have MA push. And final charge have only 0.25 rotation, like in twisted sonic.

When I do Demon's Sonic, I interrupt when would have been a normal Sonic 34-23. Since interrupted trick notation is to be used to explain what is being cut off at what time, I explain that a Sonic Normal 1.0 34-23 would have been done if not for the fact that the last part of a Passaround Normal 0.5 23-12 takes place before the Sonic finishes. There is no feeling of 34-24 in the trick, just a cutoff 34-23. The fingers do not feel at all like a Sonic clip.

The Passaround part could be in question too, but Pass Reverse no longer makes sense. The feel of the trick is not much like an actual Pass Reverse 23-12, so I'll use Passaround instead. The end of the 23-12 transition feels more like the end of a horizontal Passaround.

For me, using interrupted trick notation seems like it should either use what could have been done fully if not for being interrupted, or what the trick(s) actually feel like when doing them. Sure, feeling is arbitrary, but using Pass Reverse no longer makes any sense to me since Passaround Reverse is not what my fingers are feeling that they are doing. The 23-12 transition just has the pen bouncing around between fingers, the pen is, for awhile, moving free from any finger control. That is quite different than the deliberate motion and full involvment of the fingers that Pass Reverse has throughout the entire trick.

Edit:
:P I've got to learn to edit these kinds of posts down sometime.

To sum up: I feel that interrupted trick notation can be used to more fully explain what the individual spinning is actually doing now, rather than trying to fit an explanation of what it should be. I agree with Zombo's above post about now being able to more precisely explain an individual style based on the actual intentions and feelings that the spinner goes through when performing a combo.

yes sketching got it right. Your intention was do a sonic 34-23, and interrupt it. No one intends to do a sonic 34-24.

Sketching, i don't understand why u think that pass rev don't makes sence. I don't agree with u about passaround. I don't see in my demon sonic any passaround moves, it looks like just pass rev. I think u just do demon sonic in some another way (style). So, for my demon sonic, best breakdown is Sonic normal 34-23 [p][s 0.5] ~ charge normal 24 [s 0.25] ~ pass rev 24-12 [c][s0,5] ~ charge normal 12 [s 0.25]. Maybe u use another way to push pen after sonic, so for u your breakdown can be more right.

No problem, which is why I started everything out by saying that this is how "I've been thinking about Demon's Sonic lately." Since there is now no need to be constricting, both breakdowns work just fine. For established hybrids with names, I'm now of the view that it is more about the overall look of the tricks.

...Fake Double is a good example: the pen really just needs to go around the Thumb, then the Index finger, and do 2 rotations. How you get to that point is up to you.

Here's a bit more about the Pass Reverse portion, just you can hopefully get a better idea of what I am thinking about...
- In Pass Reverse, the pen is held by the fingers at all times: 2 fingers to begin with, 3 fingers while the pen moves around, 2 fingers to end with.
- In Passaround, there is a time when the pen is moving around a finger without being held. That's the main reason why it is Passaround Normal and not Pass Reverse.
- In Demon's Sonic, the pen is freely moving around and under the Middle finger, so calling it Passaround Normal makes more sense to me. It includes the portion where the pen is freely moving around the Middle finger, and the catch.

When i'm doing demon sonic, after sonic 34-23 i do pass rev 24-12. In starting position i hold pen with 2 finger (24), in the middle of the trick i hold pen with 3 fingers (124) and in final position i hold pen with 2 fingers (12).
Your description of demon sonic better for Eriror's demon sonic, he doing it like u say, with passaround move.
