* Driver skill: A skilled driver will consistently achieve better times than a novice.
* Track conditions: Temperature, altitude, and track surface will all affect performance.
* Vehicle condition: Even a "stock" car can have slight variations in tune or component wear that affect performance.
* Specific options: Minor option variations could slightly influence the outcome.
Therefore, while 15.0-15.5 seconds is a good estimate, consider it a range, not a precise figure.
