Just played it, and it looked as if many secondary positions were in use, e.g. the front pins at OAK#2 and OAK#3.
Not sure about the/all pin positions, but this is a brand new CTTH set-up - I received a best score (white background) at each hole, even when I missed the green.
Add, in the CC tournament set-up, there are three OAK CTTHs now, 2x front and 1x back.
