Actually, what various posters suggested was that processing the rover postions using different CORS files would somehow make a large improvement in results. In that scenario, the identical observations would be processed against observations logged at two or more CORS sites. The multipath effects at the unknown point in the cluttered urban setting should be identical for all of those vector solutions, I'd think.
