#
# MTB_factor tweaks/trims MTB approach of the profile by preferring/penalizing in progressive order
# nonpaved - preferred
# not paved - little preferred
# paved - little penalized
# mainroads - penalized
#
# MTB_factor can be used for one-time tweaking of routing profile for particular trip,
# or trimming of the profile according to biker preferencing without need of profile deep insight
#
# Positive values progessively promote/penalize roads in favour of MTB riding.
# Negative value has the opposite effect, preferring mainroads and penalizing unpaved roads.
# This effect is somewhat similar to iswet=1 ( *) wet weather mode ),
# but does not distinguish particular road classes / surfaces / smoothness,
# aside of mentioned schema below.
# The calculated values below is added to the costfactor.
# + MTB_factor for main roads (tertiaries and better),
# + 0.33 * MTB_factor for paved roads,
# - 0.33 * MTB_factor for not paved/not unpaved roads,
# - MTB_factor * ( 1 + 0.33 * smoothnesspenalty ) for unpaved roads. - at MTB_factor 3.0 smootheness is ignored
#
# Default is 0.0 = no effect.
# Recommended -0.5 - +1.0
# Reasonable -2.0 .. +3.0,
#
# Final costfactor is kept >= 1 for final costfacto values.
