Thanks for the replies,folks.
The chart I was referring to is in Nick Borg's book, "Off the Charts".
The chart allows you to plot a graph to get a quick idea if the pace of a race was picking up or slowing down as the distance increased.
Ex: :23 :46 1:10 1:35 1:47 (1 1/8 m)
Fractions 23 * 23 * 24 * 25 * 12
------------------------------------------------ 1:47
-------------------------------- 1:35
1:10
46
23
The pace stayed even for the first 6f. and then picked up even though the fractions slowed down.
It's hard to visualize without an actual graph but it is easy to follow in the book.
