Trick names and rotations

In each trick infobox, are four kinds of trick names: UPSB name, international other names, JEB name, and domestic other names shown. Forum's official trick names, according to their written convention, are notated accompanying rotations of tricks performed in the videos.

"UPSB names" are basically official trick names defined by UPSB wiki, recognized in pen spinning communities across the world.

The starting position in fingerslot of a trick must be two or less, because it is not able to spin technically, if the pen held by three or more fingers. To hold the pen at least two fingers are needed, and for example, it seems that in so-called writing position the pen is held only by the index and middle finger, in which the thumb does merely touch the pen that has already been fixed by the two fingers. Consequently, tick names involve fingerslots made up of two fingers at most such as T, 12, 24, and not T12, in PSTD.

Japanese notation convention is organized by aysh of Pen Spinning Reference Room, which is originally attributed to works of Japanese pen spinners in the early days including Hideaki Kondoh and Crasher. The naming system is seldom updated in the Japanese community, and there are no official organizations to adapt its convention to changes in the pen spinning world. Although it is not strictly maintained or managed, pen spinners in JEB are familiar with this nomenclature, after which this "JEB name" is given. In these years, instead of just modifying their traditional naming system, Japanese people started to borrow some trick names from the international convention, and also come up with many two or four-letter abbreviations which sound rather informal.

Ignoring the fact that Japanese naming convention counts rotations of spins in a trick not in figures but in terms such as "singleaxel" for 1.5, "triple" for 3.0, "decuple" for 10.0, etc., in Pen Spininng Trick Directory total spins are counted in figure, making descriptions much briefer. Nonetheless, the term halfwindmill is not written as "windmill 0.5", for it is not actually defined as a windmill trick with 0.5 rotations, but is "halfwindmill" exclusively.

Finally, the followings are what the visitors should be aware of before they refer to trick names later in the website, which are related to the four kinds of trick names:

There are some official names with "(V)-" put on its head, which indicates that the trick is a minor variation of the trick name excluding "(V)-", although this manner is not an official way, and it will not be understood among the general pen spinning communities.
To some trick names are added "(possible)" so as to avoid giving a strong statement when the administrator is not sure whether or not those trick names are actually used, able to be recognized, comprehensible.
Direction of spins in a trick infobox is mentioned as one performed with the right hand in order just to render descriptions compact.
Some trick names are lacking their number of rotations, which the administrator is not very sure how many rotations those have.
