I think all calcuttas should be that the player must bid on himself, just like any other person bidding. If the player thinks that they can automatically split with the person that bought him/her it makes the calcutta money lower than if the player had to bid on their self just like all the rest of the bidders. In my opinion the calcutta money could be twice as much if the players had to bid just like everybody else. If you think you are going to win, you better buy yourself, because there is no guarantee someone is going to split with you.
