Quoted from pkiefert:It'd be interesting to know what the average money that is spent to qualify in A's or B's at some of these bigger tournaments are, as I bet it's higher than most people think.
At the circuit event at SFGE in Atlanta the average spend to qualify for the top 16 was $146. The least amount spent was $83 and the most was $363.
I've attached a chart showing qualifying points vs number of entries. Players further to the right and lower scored more points and are more "efficient" than players to the left or higher.
I scraped the information from the results pages to get the information. I did not have any information about how many entries were comped for volunteers, so the dollar amounts are only approximate.
