Explore detailed statistics of driver performance at Portland International Raceway, featuring tables with historical and projected start and finish positions, sparklines, averages over the last two and four years, alongside visual charts highlighting the top and bottom performers over the last 6 years.
To capture how drivers have performed over time at Portland International Raceway, I calculate the trend of their start and finish positions using linear regression. This method plots each race as a data point and draws a trend line that best fits all the data over a 6-year period. The slope of this trend line helps us understand performance trends:
