Why must the P6 be a $2 wager?

[JJP]

I think its short sighted for those venues to make the P6 a minimum $2 bet. You can bet P3s, which require far less combinations, for a buck. And the trend in most bigger exotics is allowing reduced bet size. I have to think the big betting syndicates aren't going to cut back in how much they fire through, and they'll get more of the smaller players. Just doesn't make much sense.
