Yeah no LMP1 battle is a bit of a downer, but the others look good.
LMP2 -
#31 Rebellion leads #38 JC DC by 4 points.
#38 starts 2nd, #31 starts third
Assuming that the #36 Signatech, #38 JCDC and #31 Rebellion are the top 3 - if the Signatech Alpine (which is on pole) wins the race, then #31 can finish third and it will win the title. Realistically, the #38 needs to win to take the title. And then there's the G-Drive car to consider. LMP2 will be tense.
GTE-Pro
#51 Ferrari has a 13 point lead over the #91 Porsche, and 15 over #67 Ford. So the #51 appears to have a decent enough buffer and only need 7th to take the title.
GTE-Am
#98 Aston has a 10 point lead over #77 Porsche and 11 over #61 Ferrari. They only need 5th to win the title, but there's only 4 entries. So the Aston just needs to finish for the title.
I am in no way responsible for this maths being completely wrong. Which it will be, because I did it.
