Yes and Some owners and some writers put down 1/4 mile times implying that is what they have done when it is estimated only. For example there is a Morroso and prob other calculators that give ideal time potential when you enter in details such as weight and power. For example my car in a perfect run, as in great driving, ideal car set up and traction and conditions etc is 10.2. Few cars ever get to their figure but some get close.
