I think I would be right in saying that they got rid of the split development a couple of years back, following the 2009 campaign.
I think the focus should be on next year, although anything which can be added to this year should be added, to improve things, and to help with the correlation piece.
It would be good from a sponsor/fan/driver/team morale point of view to get at least one win in, but not at any cost.
