Hypothetical question about EV and teams

[sirio11]

Lets suppose you have 3 or 4 good players with a 100% ROI in the $200 tournaments.

These players use to play all the big online tourneys. Lets suppose they make a deal. Whatever somebody wins is going to be splitted 4 ways.

Up to here, looks like the ROI should not be affected, right? and the only benefit would be to reduce the variance.

But now, suppose these 4 players will be connected via AIM, and observing each others games, and when faced with a difficult decision, all give their opinion about the best way to play the hand and the final decision is up to the player involved in the hand.

With such a deal, what percentage do you think the ROI will be increased?
