[mkgmap-dev] Strange bicycle routing

Hi, why does routing for "bicycle" and "shortest route" produce a longer route than "bicycle", "fastest route" in this example? A: N 53 03,183 - E 8 37,440 to B: N 53 03,458 - E 8 37,410 The fastest route and the pedestrian and car routes go along Mühlenstrasse as expected for 512 m. The "shortest bicycle" route detours through Schanzenstrasse and along the Welse and is 752 m long. Any ideas?
