Diabolo Terminology and Abbreviations.

[ra5se]

I prefer writing the siteswaps the same i do in juggling. (according the height of the throws)
In juggling, the 441 is 2 asynch throws at the normal 4ball pattern. Then pass one ball to the other hand. 
In diabolo 441-3d high, 2 up in the height of a normal 4d high, and 1d sun. this is how i get it. But low patterns, like with 3d the 42, is how I think of it, is 1 up in normal 4d low height, and the normal 2d shuffle. You shouldn't take my word for it, but this how I think of it.

Is there a preferred way of writing fts combinations?

I don't see the problem. The highest number always represents the amount of diabolos used in the fts sequence. Right?

So if I do 57[11][2]333.. How would you write that?

but really, just put (x) at the start.

But you can do 3high 4 (or is it 5?) 2-1 fts back to 3 high (4 is a normal throw). It doesn´t work out in siteswap (or at least I don´t know how to write it ) but it does in reality.

522 would possibly work for the above siteswap as far as pace go but when the last fts is still a 1 it doesn´t.

What is (x) supposed to mean?

Good. I have seen many places where are those terms but i didn't understand them before that.  Example RHBW-terms are useful.
