receiving, via the user interface, the identification of the compound bow;

using the processor, according to instructions programmed into and executed by the processor, to retrieve (a) a cam-to-arrow distance and (b) a right-to-D-loop distance from a database based on the identification of the compound bow; and

using the processor, according to instructions programmed into and executed by the processor, to calculate the preferred location for the peep sight based on the eye height measurement, the cam-to-arrow distance of the compound bow, and the right-to-D-loop distance of the compound bow;

wherein a vertical reference line extends from (i) a first point of contact between an upper cam and a bowstring of the compound bow, and (ii) a second point of contact between a lower cam and the bowstring of the compound bow, when the compound bow is in a drawn position;

wherein a horizontal reference line is representative of an arrow in the compound bow in the drawn position;

wherein the cam-to-arrow distance is a measurement of a vertical distance between (i) the first point of contact and (ii) the horizontal reference line; and

wherein the right-to-D-loop distance is a measurement of a horizontal distance between (i) an intersection of the vertical reference line and the horizontal reference line and (ii) a D-loop of the bowstring in the drawn position.

2. The method as recited in claim 1 , wherein the user interface is accessible via a web page.

3. The method as recited in claim 1 , wherein as part of the step of prompting the user to input the eye height measurement, instructions are provided via the user interface to facilitate such measurement by the user.

4. The method as recited in claim 1 , wherein as part of the step of prompting the user to input the identification of the compound bow, a list of known compound bows is provided to the user.

5. The method as recited in claim 1 , wherein the step of using the processor to calculate the preferred location for the peep sight includes substeps of:

calculating an angle between the horizontal reference line and a line formed by the bowstring of the compound bow that extends from the upper cam to the D-loop; and

calculating the preferred location for the peep sight relative to the D-loop based on the calculated angle and the eye height measurement.

6. A method for determining a preferred location for a peep sight on a compound bow, comprising steps of:

providing a processor programmed to execute instructions stored in a memory component;

providing a user interface in communication with the processor;

prompting a user, via the user interface, and according to instructions programmed into and executed by the processor, to input certain anatomical measurements or information;

receiving, via the user interface, the anatomical measurements or information;

using the processor, according to instructions programmed into and executed by the processor, to derive an eye height measurement from the anatomical measurements or information;

prompting the user, via the user interface, and according to instructions programmed into and executed by the processor, to input certain measurements of the compound bow;

receiving, via the user interface, the measurements of the compound bow;

using the processor, according to instructions programmed into and executed by the processor, to derive (a) a cam-to-arrow distance and (b) a right-to-D-loop distance based on the measurements of the compound bow; and

using the processor, according to instructions programmed into and executed by the processor, to calculate the preferred location for the peep sight based on the eye height measurement, the cam-to-arrow distance of the compound bow, and the right-to-D-loop distance of the compound bow;
