Robby sits 34th in owner points, with +30 over 35th (#47 car), +47 points over 36th place (#84 car) and +131 over 37th (#77 car). Robby is -80 behind 33rd (#66 car), -89 points behind 32nd (#41 car) and -100 points behind 31st (#22 car).
So here's the scenarios:
If the #84 fails to qualify RGM is locked automatically
Robby will stay inside the Top 35 if he finishes ahead of the #47 or the #84.
Robby will stay inside the Top 35 even if he gives up to 15 positions to the #84
Robby will stay inside the Top 35 even if he gives up to 10 positions to the #47
If Robby leads a lap, this will extend his lead another position.
So if Robby finished last he could still stay inside the Top 35 as long as the #84 finished no higher than 28th or the #47 finished no higher than 33rd.
