Archery Prep: Marching To A Different Tune
Keep in mind when you lengthen an arrow or increase point weight you decrease the arrow spine. And when you shorten your arrow or decrease your point weight, you increase your arrow spine. I also prefer a limb-driven rest like the Smack Down Pro, where the control cord attaches to the limb of the bow and not one that ties into your cable system. The cord can and will create drag on the cable it is tied into. You can also have issues of it slipping on the cable it is tied to.
The limb-driven rest causes no drag on your cable or string system, plus the limb-driven rest picks up the launcher arm much faster and drops it much faster, which gives you optimal rest clearance for your arrow.

My next step is to shoot the bow about 20 to 30 times at point-blank range into my bag target with a field point. This helps to set and seat the strings and cables before you start your tuning process. The next step is to make sure your tuning shaft has the exact same point weight as your broadhead and is the exact same length from nock to tip as your arrows with your broadhead attached.
There are two types of paper tuning for a bow. One is tuning with a bare shaft, and the other is with a fletched shaft. I prefer a bare-shaft test, and the reason being is if your bow will shoot a bullet hole with a bare shaft, it should shoot any point accurately as long as it weighs the same and spins straight.
The less the fletching on your arrows have to correct arrow flight at launch, the quicker your arrow will recover, and the straighter it will fly. If you get a bullet hole with a bare shaft but you get a tear with a fletched shaft, you are getting contact somewhere in the launch cycle. This is something that often frustrates the average guy who is doing his or her own tuning. You think you have a tuning issue, when in reality you have a fletching contact issue. Not all drop-away rests truly drop away in time. It is also possible for a fletched arrow tune to be slightly less than perfect due to the much larger hole a fletched shaft creates in the paper.
A bare-shaft bullet hole does not lie.
Another great new feature of the Evolved Cam system is that it has a floating yoke system on both cams to balance and control cam lean. Cam lean has always been an issue with binary-cam systems without a yoke system to adjust them. Uncontrolled cam lean will result in not being able to tune the bow properly, and if severe enough, it will cause the bow to derail at draw or after the shot.
The only cure for this condition is to shim or move the cams left or right by having to completely disassemble the bow. This can be tricky even for some bow techs. Once the bow shoots a bare shaft properly, I attach my sights and stabilizer and any other accessories to my bow. I then sight-in my fletched shaft with field point at 20 yards, and then I pull that arrow and mark the hole with a piece of tape.
Next, I shoot the bare shaft at the exact same point of aim as the fletched shaft. I then mark that spot and shoot my broadhead, making sure it spins straight first.
It is not wise to shoot multiple carbon arrows at the exact same spot, especially with broadheads. Once your bow will shoot a bare shaft, fletched shaft and broadhead on a fletched shaft to the same point of aim at 20 yards, your bow is tuned. The next step is to fine tune your sights with your broadheads at different yardages. I shoot one pin sighted-in at 25 yards, and with my setup it gives me a plus or minus 1-inch margin of error from 0 to 33 yards. Anytime you change anything on your bow, you must retune, no matter how simple you think the change may be.
I contacted Kris Wall, a well-known bow tech in the Athens area and regular contributor and problem solver at the Woodys web board forum. A bare shaft has zero steering from the front and the rear, while a fletched broadhead shaft has steering from both the front and the back.

You may ask how they behave the same then. A fletched broadhead that comes out of the bow the same way, point right, nock left, will also continue to plane to the right because wind from the front of the arrow is pushing the broadhead in that direction. The fletching can correct some of it, but not all of it, if the bow is out of tune.
So, I prefer bare-shaft tuning to get the arrow coming out of the bow as straight as possible. I do like to keep my speeds in the to fps range for fixed heads. A summary of recommendations made by an independent inquiry into police transformation in Northern Ireland has been included.

A good intervention will have the capacity for response to the individual student built in. In this sense, fidelity to the response contingencies of the intervention is the crucial factor.
A further post may be needed to explain how this can work. In short, skills and knowledge can be analysed by their components, and weak components taught to fluency before they are recombined. The impact of this approach in special education is well documented. For example:. Johnson, K. Julian Elliot has written extensively about the use of a dyslexia label being counter-productive. The emotional, social and political functions of this label exist, but they do not actually enhance the learning of those to whom it is applied.
In particular, Elliot points out that the folkloric definition of discrepant IQ has no evidence in the literature. Stanovich rejects this notion as well. They should never be a substitute for explicit systematic teaching of reading — except where they are adaptations to overcome a motor disability.
