Where there is divergence, it's usually due to bugs. The 'matching' is basically just a trip planner along OSM, so generally it finds some trips that travel along the shape points of the transit line. If there's no trip found within a reasonable distance, then we generate errors and the data integrators will have to take a look. We've fixed a couple of issues in OSM already, usually it was different rail stretches (ways) not being connected.
