Race Mode; Speed - Velocitek Prostart Manual

The early / late bar graph provides a graphical representation for your estimated location at the gun
based on your current position, speed, Course Over Ground, and the time remaining in the countdown.
The bar graph extends above the illustrated line if the calculated future location is over the line and
below the illustrated line if your future location is under the line. When no bar graph segments are
showing - the "0" display - your estimated future location at the gun is between the line and 2 meters
below the line. Each segment shown represents +/- 2m from this "0" location. For example, 2 bar graph
segments showing above the line represents that you are predicted to be between 2m and 4m over the
line at go. For simplicity's sake this algorithm assumes the line to be of infinite length so it does not
compensate for any situation where your current heading would not take you through the starting line.
The goal is to eliminate all the bar segments around the perimeter and only have the semicircles
showing. This indicates that at your current speed and heading you are expected to be within 2 meters
of the line at the gun.

Race mode displays information crucial during the race: speed, magnetic heading or COG, and heel
angle.
