I'm very skeptical about the accuracy and reliability of his results.

I need to know more about the situation.

First of all, I need to know HOW the track was circled.

Was it by foot? By car? By horse? By a dog?

- - The current men's world record in the Mile Run

is 3 minutes 43 seconds.

- - My friend reported research showing that it really

only requires about 22% of that much time.

- - His data and his methods need some peer review.
