each skier based on type of second segment pull requested Numbers are a
suggested starting point only and are boat dependent May have to start or
make adjustments outside of suggested values Driver may adjust as necessary
to obtain actual times in second segment |
S2%
(suggested starting point): Fast second segment = Faster 40 to Faster 60
Return to Baseline = Zero (Option 2)
S2 FINE – Fine RPM adjust for second segment – normally only used when
option 2 has been selected |

X8u
|
Skier
|
The
manufacturer’s X8u setting may be adjusted up or down by up to 30% (rounded)
of the manufacturer setting and adjustment zones as published. Any change
from the manufacturer’s setting shall be communicated by the skier before the
first jump. One additional adjustment may be made after the skier’s 1st jump only. |
X8u
(UP) controls the rate of additional rpm added once the jump switch closes.
The higher the number, the lower the rate rpm is added. With a higher number,
it will take longer for the full additional rpm to be reached (softer at the
start/stronger near the ramp). |
|
X8d
|
Skier
|
Skier can choose at the dock before 1st jump. No further change |
X8d
(DOWN) controls the timing of the rpm drop in the second segment. The higher
the number, the longer it will take for the boat to begin controlling speed. |
