Hello,
the specified range is correct. One place in the code uses the parameter to
interpolate between two alternative values using formulas such as:

v = lcCooperative * cooperative Speed + (1 - lcCooperative) *
uncooperativeSpeed

This might indeed lead to odd behavior if lcCooperative is larger than 1.

regards,
Jakob
