== "Started Rapid Growth" == 

 The description of his physical characteristics at the age of 4 (where he is 5' 4" tall and is described as "start[ing] rapid growth") is clearly erroneous. If someone is 5' 4" at the age of 4, rapid growth must necessarily have started during a prior period. (Technically, one could envision a scenario where, e.g., rapid growth begins during month 1 of age 4 and 5' 4" of height is reached during month 12 of age 4. However, given the unit of measurement (years rather than months), the chart cannot accomodate such a scenario without further elaboration. As it stands, the best move would be to simply delete that description. Perhaps it could be better described as "height and weight records reflect first evidence of rapid growth"
