On Fast Archery or Speed Shooting

“Speed shooting" archery is a style of archery where you knock, draw, and fire arrows at a rapid pace; it is also typically practiced while holding your other shafts in the hand which is also drawing the string (but this location of hold is not always the case).

The style of a culture's archy, as with many of that culture's features, is a product of the environment in which it appears. 

Take the cable-backed bow and the composite bow as examples. The former is a bow "backed" with a sinew cable, not glued to the bow's surface; it was used among primitive Inuit cultures and to a lesser extent by other non-Arctic dwelling cultures; the reason for this is due to the difficulty of using animal-derived glues in cold climates—making the glue and maintaining the glue's fluid viscosity long enough for it to saturate sinew fibers; these are problems that are not as difficult to deal with in environments where composite bows appear, such as the Steppes of Mongolia or further south in areas of North America.

Fast archery—not used by Intuit (to my knowledge)—would have been a practical skill in an environment where you are at war with other people which are also using bows and arrows against you—a skilled archer is more than a lethal menace on the field.

As a ground hunter, being well trained in both holding additional arrows in the draw hand and being able to shoot them accurately eliminates the need for bow quivers and hunting quivers in general.

A primitive, isolated tribe, whose name escapes me, who are not at war with other primitive tribes, which do hunt deer and boar, not only shoot one arrow without holding the other arrows in their draw hand but also shoot on the "inside" of their bows.
