Just in case the earlier explanation didn't stick... These performances are adjusted for height and weight only (read more closely) not anything individual or school related. Look at the top 10....
name, school height, weight, and then "z scores" for various speed/strength tests relative to the adjusted mean. The last number is the total standard deviations by which the person exceeds the average in the tests. Look at #4 and 6, particularly. This has to be a BIG selling point for our physical development program. Come here and you can be the best developed athlete in the nation, even as a ** or *** recruit. NOT bad at ALL!!
