-# *** Based on Trekking profile, added flag driven customizations

-# 2014-10-10 (c) Poutnik
-# Route_foot related hints were improved with usage of Hiking.brf from below and by Arndt comment
-# http://pastebin.com/YLpkGVD4
-# http://forum.openstreetmap.org/viewtopic.php?pid=447507#p447507
-#
-# 2014-10-10 v1.1 - changed hiking route preference logic
-# 1.2 - fixed preference counting bug
-# 2014-10-11 1.3 - adding foot route to hiking routes,  
-# fixed ferry cost to respect initial cost triggerring.
-#      added bikeaccess,  added shortest way mode,  code cleanup
-# 2014-10-12: v1.4 - involving turncosts and way/node initial costs as orientation/decision penalties,
-#           but turning them off for sticking to hiking routes as extra preference,
-#           tweaking cost preferences
-# 2014-10-13 v1.5 
-# redesigned route preference policy - turncost turned off even for nonsticky but preferred hiking routes
-# cost tweaking.
-# removed uniform cost=1 for sticky hiking routes, to distinguish quality
-# giving penalty 1 for non hiking routes at sticky hiking routes.
-# used not round costs to often trigger initial cost calculation
-#v1.51 - bugfix of redundant routing penalty
-#v 1.6 - initialcost penalty only for sticking routes, decreased way penalties for preferring routes
-# 31/5/2015 v 1.7 ALFA - sac_scale + sac_scale_limit implemented 
-# 10/6/2015 v1.7.1 ALFA - sac_scale improved, MTB scale integrated to SAC scale
-#                         sac_scale_preferred implemented, with progressive penalizing for SAC <> SAC preferred
-# 10/6/2015 v1.7.2 BETA - Fixed general way access penalties

+# MTB_factor tweaks/trims MTB approach of the profile  by preferring/penalizing in progressive order
+# nonpaved  - 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.

+# Hiking Version 1.6 ALFA
+# 2014-10-10 (c) Poutnik
+# Route_foot related hints were improved with usage of Hiking.brf from below and by Arndt comment
+# http://pastebin.com/YLpkGVD4
+# http://forum.openstreetmap.org/viewtopic.php?pid=447507#p447507
+#
+# 2014-10-10 v1.1 - changed hiking route preference logic
+# 1.2 - fixed preference counting bug
+# 2014-10-11 1.3 - adding foot route to hiking routes,  
+# fixed ferry cost to respect initial cost triggerring.
+#      added bikeaccess,  added shortest way mode,  code cleanup
+# 2014-10-12: v1.4 - involving turncosts and way/node initial costs as orientation/decision penalties,
+#           but turning them off for sticking to hiking routes as extra preference,
+#           tweaking cost preferences
+# 2014-10-13 v1.5 
+# redesigned route preference policy - turncost turned off even for nonsticky but preferred hiking routes
+# cost tweaking.
+# removed uniform cost=1 for sticky hiking routes, to distinguish quality
+# giving penalty 1 for non hiking routes at sticky hiking routes.
+# used not round costs to often trigger initial cost calculation
+#v1.51 - bugfix of redundant routing penalty
+#v 1.6 - initialcost penalty only for sticking routes, decreased way penalties for preferring routes
+# 31/5/2015 v 1.7 ALFA  + sac_scale + sac_scale_limit implemented 
+# 10/6/2015 v1.7.1 ALFA * sac_scale improved
+#                        + MTB scale integrated to SAC scale
+#                       + sac_scale_preferred implemented, with progressive penalizing for SAC <> SAC preferred
+# 10/6/2015 v1.7.2 BETA ! Fixed general way access penalties
+# 15/6/2015 v1.7.3 BETA * SAC-MTB scale integration reevaluated, increased MTB scale penalty
+#                       * MTB scale penalty used as fallback if no SAC rating
+# 16/6/2015 v1.7.4 ALFA * Optimized SAC logic 
+# 17/6/2015 v1.7.5 BETA + Track penalty system
+# 20/6/2015 v1.7.6 RELEASE * Modified and simplified route preferencing
+# 01/12/2015 v1.8.1 ALFA   +ported MTB_factor from bicycle Trekking template, renamed for hiking context to Offroad_factor
+# 02/4/2016 v1.8.2 ALFA   +implemented path preference factor , try 20.0. Default 0.0 has no effect
+# 3/5/2016  v1.8.3 BETA   +implemented navigation hint support
+# 7/5/2016  v1.8.4 RELEASE +implemented navigation hint support ftom BRouter 1.4
+# 10/5/2016 v1.8.6 BETA   * decreased turnInstructionCatchingRange from default 40 to 20
+# 18/5/2016  v1.8.7 BETA   ! Fixed down/uphillcostfactors for shortest_way - to be really shortest
