Hello,
the section contained some explanations that were not up-to-date with
version 1.0.0. (until just now)
I recommend that you read it again.

The speedFactor is sampled for every vehicle (flow or otherwise). However,
if you set the deviation value to 0.0
(either by setting speedDev="0" or speedFactor="normc(x,0.0,y,z)") then the
value will be a constant x for all vehicles of that type.

The speedFactor must be positive and within the capping boundaries.

regards,
Jakob
