DFS NASCAR: Track Data Legend
A quick-reference guide to what everything means with regard to the track breakdown data Matt Selz uses for DFS NASCAR.
Track Breakdown Legend
A new season brings new opportunities to pour over data in an effort to make ourselves better fantasy players. NASCAR is no different. The 2018 year will see changes in both the articles produced for NASCAR at Fantasy Alarm but also the data we put in the track breakdowns for each week. This legend will help you to understand what each of the columns mean so you are better equipped to parse the data you want to before setting your lineups for each race.
What do the stats/abbreviations mean?
Driver: Name of each driver competing in that week’s race
Races: How many races each driver raced in that particular table
Avg. Start: The average starting position for that driver over that span of races for that race, track, or track type.
Avg. Run Pos.: The average position on the track for that driver during all of the green flag laps run in that span of races. It helps to show how a driver moves throughout the race compared to starting and finishing positions.
Avg. Finish: The average finishing position for that driver over that span of race for that race, track, or track type.
Wins: Number of wins for that driver during that span of races.
Top 5s: Number of top-five finishes for that driver during that span of races.
Top 10s: Number of top-10 finishes for that driver during that span of races.
Top 15s: Number of top-15 finishes for that driver during that span of races.
Top 20s: Number of top-20 finishes for that driver during that span of races.
Laps Led: Total number of laps led (finished the lap in first place) for that driver during that span of races.
Fast Laps: Total number of laps clocked as the fastest car on the track regardless of position in the field.
Top 15 rate: Percentage of laps run in top-15 spots compared to total laps run during that span of races. Example: Top 15 rate shows 80%, that means that 80% of that drivers laps run over the course of that number of races, they were in the top-15 positions on the track.
Pass Diff.: This is the total sum of positions gained or lost over the course of that span of races. Example: Pass Diff. shows 13. This means that Driver A has passed 13 more cars total over that span of races than he was passed by in that same span. This is a new statistic for us and it will take a few races to get a better feel for the best measures of this metric.
Avg. Rating: The average driver rating for that driver during the span of races in the table. Driver rating is a combined calculation to express how well a driver did in a race. A good explanation can be found on NASCAR.com or using the link in my Intro to NASCAR DFS article. A perfect race rating-wise is 150 with the low rating near 30.
High Rating: Highest driver rating achieved in a single race during the span of races in the table.
Low Rating: Lowest driver rating achieved in a single race during the span of races in the table.
Pos. Diff.: Position Differential is the difference between starting position and finishing position. A higher positive mark indicates a driver moved up through the pack well, whereas a negative mark indicates a driver went backwards through the pack during the race, either by crashing or just not having a fast enough car.
Laps Led Pts/Race: A calculation to show how many average laps led points a driver gets over the course of a race for that particular table. It is calculated by multiplying the total in the laps led column by 0.25 (point value for one lap led on DraftKings) then that total is divided by the number of races driven.
High to Avg Rating: Shows the difference between the driver’s highest driver rating and their average rating. A smaller number than the Low to Avg Rating column has means that driver has more often performed closer to their high average than their low.
Low to Avg Rating: Shows the difference between the driver’s lowest driver rating and their average rating. A smaller number than the High to Avg Rating column has means that driver has more often performed closer to their low average than their high.
Top 10 Value: A ranking of the top five drivers based on FPPK (Fantasy Points Per $1,000 of salary). The higher the number the more bang for your buck a driver gives you. They are calculated by taking average fantasy points per race and dividing that by their salary/$1,000. Example: Driver A averages 60 FPPR and costs $10,000 for that race. His Value or FPPK is 60/($10,000/$1,000)= 6.0 Value. Anything that’s 4.0 or higher is a really good mark.
Bottom 10 Value: The same calculation as the Top 10 Value statistic, however it is simply the ranking of the 10 smallest value marks in the field for that race.
17 Race DK Pts.: A listing of the actual DraftKings points put up by each active driver that raced in that race in 2017.
Season Avg. DK Pts.: A listing of each driver’s average fantasy points output per race for the season regardless of track or track type.
DK Pts. +/- Season Avg.: This stat shows just how a driver fared in the previous running of that same race against their season average. Example: Driver A scores 55 points in Race A but averages 40 points per race for the season. This column will show a positive 15 indicating that he outperformed his season average at that race. Crashes will exaggerate negative results.
Average +/-: This stat gives the average over or under performance by compared to the season averages for that race. Example: the Average +/- shows 15 meaning the drivers (on average) outscored or underscored their season averages by 15 points. So a driver who averages 40 points per race could score between 25-55 points if the average holds true.
