I don't know... from what I've heard the "mass exodus" (or 1994 or of 2001) was for the most part a myth. Some probably did leave (in 2001), and the ones that left were probably talking on the internet, making the "move" out of ROCOR seem bigger or more significant than it was. There seems to have always been this type of problem--a small but vocal group leaves ROCOR, leaving the impression that the split is bigger than it actually is. The problem is that they are now coming closer and closer together. Back in 2001 (addressing the reaction of some to ROCOR's 2000 documents), ROCOR said the following:
Thus, with regret our whole Church has had to endure powerful disturbances hitherto unseen. As if from deep within the bosom of the body of the Church cracks began to appear, though they have not yet developed into deep fissures. We look on with fear as in places they are trying to transform these chinks into rifts which split apart not only the flock, but even the clergy.
I think this fear has been validated. That doesn't necessarily mean there was a mass exodus, though. If there was, I too would like to know how many left, and also where they went to? I know of no jurisdiction (traditionalist or otherwise) that speaks of suddenly having an influx of thousands upon thousands of disgruntled ROCORites around 2000/2001.
