i think pinnacle is wrong here. the only thing used for qual matchups is the qual time, not starting position.
here are their rules from their website.
i don't think its going to matter anyways as
mayfield was much faster in practice than biffle and will likely beat him in qual today.
NASCAR Qualifiers:
For qualifying matchups, only the times posted during the qualifying session are used.
If a driver starts a lap but does not post a time, the driver is deemed to finish last, losing to all drivers who post a time. If more than one driver starts a lap but does not post a time, all such drivers are tied.
If a driver does not cross the start line, all wagers that specify that driver are considered "no action".
Disqualifications that occur more than 30 minutes after the qualifying session has ended are not recognized for wagering purposes.
If the two drivers in a wagering matchup post the same time to the nearest thousandth of a second, the matchup will be graded as No Action and all monies refunded. In this situation, the starting positions assigned by NASCAR are not relevant for wagering purposes.
Wagering lines on qualifying matchups will be considered closed at the start of the first practice. Any wagers made after the start of the first practice session will be graded as No Action and all monies refunded
