If we go by the same rationale of players scoring over 300 being the only ones that are actually playing the tournament (as opposed to dipping in for a few encounters to pick up FS rewards), then the number is different. With your numbers I can look at those scoring over 500. Out of those 2,680 people there are 360 scoring over 2,500, which is 13.4%. I would guess that if you took all those people scoring above 300, then you might get a similar result - i.e. about 10-12% of tournament players will be adversely affected.Standing this stupid ground that only a small percentage of players are affected, which looking at my server, 1.7%, is true, but it wouldn't surprise me if these players represent half the financial base of this server.
This is the minority, but it isn't a tiny percentage.
