Kansas Rain Sends NASCAR’s 70/30 Performance Metric Back to the Forefront

The metric again set the starting grid and its repeated playoff use has raised questions about fairness and possible rule changes in the offseason.

Overview

NASCAR’s performance metric weights a car owner’s previous-race finish 70% and the owner standings 30% to determine qualifying order and starting lineups when qualifying is canceled.
Qualifying at Kansas was called off and the metric set the field, the third of four Chase races where the formula has determined starting spots.
Ryan Blaney said he is growing frustrated after a Bristol DNF and earlier poor finishes pushed his No. 12 car to start 25th in Kansas and hurt his championship chances.
Other drivers have voiced complaints after recent cancellations produced sharply different starting positions than the season standings would have produced.
NASCAR Cup Series managing director Brad Moran said the sport will solicit industry input in the offseason and may adjust the percentages or the system but will not make an immediate change.
