So now you are admitting that the grid price would be lower than the over all market price for cattle during a given week if the cash market was EVER discriminated against.  Sounds like the makings of fraud to me.

Keep talking about the competition in the cattle markets.  The market concentration is huge.  You are not going to convince anyone with a brain (including yourself) that there is not the potential for market power in the cattle business with the current cocentration of buyers.
