t-and-f: Re: Hurdle heights

[McDonald, Craig Richard]

Hello:

Read your article with interest on t-and-f, you stated:

"As it stands currently in the short hurdles the men are required to clear a

hurdle 122% higher than their leg length, and the women 100% in the long 
hurdles it is 103% to 91%."

How did you derive these relative percents?  What were the average leg
lengths used?

Craig
