OH, this will be a good one.
Besides Vegas money, might we also consider how many active teams the LO has that are paying into their pay back fund (it comes out of the money you return with the weekly scoresheet), how long has that APA area been up and running, what is the weekly match fee amount due(varies widely throughout the country), does the LO pay the $250 per team Vegas registration fee or require the teams to pay it, does the area conduct any other tournament events which also receive money pay back, does the area have any TOP GUN or MVP program that returns money to the players, etc.
Often many more factors than just the amount of the check given for Vegas expenses.
