HOW TO PLACE MARKERS

Click here to download a print a copy of this page.

Placing markers on the reflex graphs is important in obtaining accurate results. Markers are placed at two locations. The first marker is placed at the Pre-fire as defined by the reflex curve where the line is coming back up from the negative chart to touch the baseline (0). The second marker is placed at the Fire as defined by the reflex curve where the upward bell curve graph is coming down to touch the baseline again. It is important to note that the upward (positive) bell shape graph is the reflex curve. All the other parts of the graphs are accessory noise. Each person will have a unique reflex graph and results will vary from individual. Therefore, when you have a reflex curve that does not come back down to the baseline, it may be difficult to determine where to place the second marker. Simply extrapolate the curve to the baseline with a straight edge (by placing a piece of paper or business card along the downward curve) and where the extrapolated curve touches the baseline is where the second marker should be placed.

Below are examples of marker placements. Where the blue line is, is where the extrapolated curve should start and where the blue line ends, is where the second marker should be place as noted by a dark black circle.

Example 1: Perfect reflex curve. Markers are placed as noted.

Example 2: Reflex Curve does not come back down to base line. Second marker is place at where the curve has been extrapolated to the base line.

Example 3: Reflex curve has a lot of accessory noise and again second marker is place where extrapolated curve ends.
