  • This factor is related to factor 2 but counts actual changes in points leadership rather than the number of unique drivers to lead over the season
  • 1986 and 2010 topped this factor with 10 changes in points leadership over the season. (Note that a single leader over the season is counted as a single lead change rather than no lead changes)
