Ai Ogura is winning Austria or Silverstone and a track in Asia.
A quick search on google says that Austria leads the longest race distance on the calendar at 121.74km and Silverstone coming in at 118km.
Le Mans is 113km and Ai Ogura was the fastest guy in the last 5 laps and was gaining quickly on MB72 and JM89 with drive grip to spare. 8 more kilometers and Ogura would have surely passed even Martin.
Of course there are all sorts of factors like track layout and temperature and who favors the certain track more, but in a mathematical and logical sense, a longer race distance favors Ogura. Sorry for the clickbaity title.
I say a track in Asia because during the summer months, tire preservation is critical and Ogura does well with Asian tracks.
