When using a higher hc, the "search for alternatives" (my terminology) is stopped earlier. It does not follow all roads (paths according the mathemathical wording) until it finds another that, when adding it to the route, leads to an even faster route in total, where in this case faster=shorter => shortest path. Please read this (very high overview) article in wikipedia: https://en.wikipedia.org/wiki/A*_search_algorithm Use in Google for example the search term "shortest path A* algorithm" and look for the images and videos, which to some are more explanatory than reading a page of text. > when I drive by car I am mostly not in a hurry and would like to be lead > to small unknown roads that even shorten my way - so I mostly choose gas > saving (in fact, that is what I love osmand the most for!). one problem > here still remains: the time calculations become completely wrong the > moment I switch for gas saving. they are more than 50% to high (while > without they are pretty much exact). a trip which takes about 3hours20 may > be displayed with 5hours10. that shure helps not starting too late - but > arriving way too early doesn't help either ;-) how can I change that > without getting into even bigger problems? thank you! > > I did read your questions/remarks/issues related to this earlier. When looking at the routing.xml it is "just" a different setting of the parameters. Therefore I think it is a bug in the calculation: the route may be correct, but OsmAnd does something strange with the route time calculation.
