Let's assume that a player has a high ranking from playing SK. The player enters a full-ASL tournament and because he takes low percentage shots activating SAN, doesn't bypass, doesn't late CX, and plays as if no quarter were in effect when it is not, he loses in the first round to a much lower ranked player. The ranking for the SK player drops and the full-ASL player goes up. In the next round, the newly higher ranked ASL player draws a proficient player that spanks him. He drops back down and player C gets a point boost. At the end of the day, A moves down, B stays pretty much where he was, and C moves up in ranking. The SK player that ventures into the deep water gets adjusted.
So B thinks, I can get a higher seed by playing in a bunch of SK tournaments. He does and wins, gaining significant points. B enters a full-ASL tournament, garners a high seed, and loses in the first round. Points gone, or at least some of them. He gets adjusted.
The whole point of seeding is to get the top four players in the semis and the top two players in the finals. That is what the tournament should try to set up. Don't pair the two best players in the first round. A enters with a high rating. Play any full ASL? No. OK, you are the 5-seed in the 8-man bracket. The TD can use other information other than the ranking to seed his tournament. Reputation, scope of scenarios, years playing or not, etc. The TD ... probably a smart guy.
