ok. your presentation says that you used a single vantage point. Do you know where the filtering happened? Is it possible that it could be "not far from you", i.e. maybe your upstream provider was filtering on some routers to some destination, and not filtering for some other routers for some other destinations (i.e. different peers). That might not be the case, I'm just trying to get a better understanding of your results.
