Few runners took their time in meters - only yards. In 1962 Bob Hayes tied the world record at 9.2.
In Hayden Fry's book Hayden Fry: A High Porch Picnic Fry writes "He was from Highland Park High School in Dallas and had 9.4 speed in the 100, but he was so thin I called him my pipe cleaner."
I well remember the talk around Dallas when this happened and the often-referenced 9.4 speed.
