When folks speak of "point on", are they meaning "point blank", where the arrow point is directly on the bull and when shot will hit the bull? To put it into context, we're talking about the realm of 3 under gap shooting.

Point on is as you described. Point blank is usually in reference to an extremely close distance.

In rifle shooting, "point blank" means that you know the trajectory of the bullet and sight in so that by holding the rifle sights on the desired impact point you know out to a certain range the bullet will hit above or below or on the position the sight is being held on. For rifle hunting deer for example, If the kill zone of the deer is either 3" above or 3" below the center of the chest behind the shoulder, you can hold right in the center of the chest on any distance out to your point blank distance and know you will get a "kill" with out worrying about how far you are shooting. All you have to know is what that point blank distance is. In the example above, as you shoot beyond your point blank distance, the bullet will drop below the arbitrary 3" used. To my knowledge this is mostly a hunting technique so you don't have to figure a hold over or under in order to make a shot into the "kill" zone.
I'm not sure that there is much applicability in archery, unless using a sight.

Mike, In "Masters of the Barebow I", Rod Jenkins uses the term "point on" to describe the distance from the target where you can put your arrow in the kill zone and it will hit there. In his example, at 40 yards his set up is "point on".

"Point on" is all about sight picture and distance. When you put the tip of your arrow on the spot and that's where it goes then you are point on. Knowing your point on can be a tremendous help in shooting.
