The cheaper the bet gets, the more the bettors will spread it around, theoretically flattening the payoffs to the extent that none of them can cover the 'take' and everyone loses. This only begins to make sense when the pools are huge and the odds are high, making it more like a lottery.
It the bet was REALLY large, payoffs could be exceptional, but consolations would be frequent. Many would probably pass on the opportunity.
Probably, neither of these make sense with $3,000 pools. So, where's the sweet spot in between? And, would it be different if pools were $10,000-$15,000 again?
Is the sweet spot the spot where the fronton nets the most, or where the bettors have the most fun? Can these both be the same spot?
