The rules say that you use the smallest value after turn 3, the middle value after turn 6 and the largest value after turn 9. Many of the VP tiles don't go from smallest to largest.
I've played assuming that the rules are incorrect as written and that you actually use the left/center/right values after the 3rd/6th/9th turns. Is this correct?
Yes. (sigh). I wonder if that went through French on the way to the new English rules.
