From my understanding, there are no rules as to how many handseals one can perform in a post or how many handseals a technique requires. Obviously if we know the handseals for the canon techniques, then you're more then free to post the exact handseals performed. But in most cases people simply put 'performed the needed handseals' and it seems to keep everyone happy, also we don't offer a list of handseals or partial details on the site. We do offer some special characteristics that allow you to perform techniques faster or even with one hand if you wanted to, so that means you'll be able to release a technique faster then someone who didn't have the special char. The special characteristic you suggested does not exist, yet. But it seems like an interesting idea...

Hand Movement

Physical Requirements: Requires no specific specialization.
Training Requirements: A 1600 word training post is required to gain this special characteristic.
Description: A skillful and convenient characteristic that is learned to those who have practiced in the art of hand speed movement in nearly all forms. There are many uses for this characteristic as it can enhance nearly all forms of specializations. It is essentially the practice of moving and manipulating your hands with expert efficiency to the point where they become a blur. With this special characteristic a ninja can perform any number of hand seals within seconds or instantly depending on the amount of seals necessary. This allows them to execute techniques faster than the opponent can perceive providing unsuspecting attacks. This technique also allows the user to draw seals and perform attacks with their weapons quicker. Lastly it allows puppeteers to maneuver and manipulate their puppets in extremely high speeds where their hands become a blur.

Solved.
