I think it's 41 because there is no need for the PCP (All 8 champions are locked in based on owner points regardless)
EDIT: With Jayski's entry list I've calculated who is locked in and who isn't based simply on owners points.
THE 3 DRIVERS WHO ARE NOT LOCKED IN NO MATTER WHAT:
Patrick: 42nd in Owners points
Bliss: 45th in Owners points
Speed: 43rd in Owners points
If the top 40 are locked in, Joe isn't locked in.
If the top 39 are locked in, Joe and Wise are not locked in.
If the top 38 are locked in, Joe, Wise, and McDowell are not locked in.
(Here's hoping Danica wrecks in the duels again and has to go home)
