It’s time to turn to the Fantasy Racing Online algorithm and see which drivers it likes the best for Sunday’s STP 500 at Martinsville Speedway. Fun Fact: the driver the algorithm has liked the most over the last three races has finished 1st, 1st, and 2nd.
There are quite a few statistics that go into the Power Index formula, including recent performance both overall and at Martinsville specifically, similar track performance, projected strength of the car, practice speeds, starting position, and a few other variables.
Here’s a quick overview of the Power Index number: essentially, zero (0) is considered average; the more negative a number is in the Power Index, the stronger that driver is considered in the Fantasy NASCAR world. The opposite holds true as well: the more above zero a driver is, the worse he is considered for Fantasy NASCAR that week.
