Based on past responses most chalkie bettors will probably tend to lean on post 4 or 5 simply because they want to leave post 6-8 out of their bets. I'm sure they wouldn't play post 4 or 5 to run out unless they were better then average players. A great player that runs out from the 4 or 5 post means a small trifecta payoff. I don't think many chalkies will respond because it has to be post 4 or 5..overall.
