total distance seems incorrect for alternative route

[karussell]

See discussion here. Also reprodicable for a different simpler route.

Have a look into this route and click on the second alternative: it will show a distance of 3.7km (somehow this is only 3.4km locally!?).

But when adding a via point into the route the distance will be 3.3km.

This is a problem only for the alternative algorithm with CH and edge-based traversal.

This bug seems to be fixed now. Last week adding a point into the route increased the distance by about 300m, this doesn't seem to be the case anymore.
