This is not that easy or cost-effective to do, IMO.
When you dump in a cheaper tournament, you're going to be out of the tournament quickly. The best would be to lose all of your games, so let's say you're two and out, 5-0 and 5-0. You've lost your $25 and that's only 10 games. So you probably need to enter a bunch of those tournaments, losing $25 for only 10 games every time. Do it 10 times to get 100 lost games in the system, and you're out $250.
Then you go to the big money tournament. They're going to have longer races and lots more players. You might need to win 40 games to get in the money and win $200, which doesn't even make up for the $250 it cost to lower your rating. To win the 1st place $800 it might require 60 games if you go through the winner's side, 100 if you go to the left side early.
You've made a couple hundred dollars, but you can only do that once in your life because you've now lost your low Fargo rating, and on top of it all you're a miserable little nit who spent weekend after weekend losing to grandmas so you could have one winning weekend. And now everyone knows it.
Very well said.
