Terri's weight: max of 200 vs. 250 

In http://msnbc.msn.com/id/7306483/site/newsweek , Arian Campo-Flores writes:

By 1981, in her senior year at an all-girls Roman Catholic high school, she had reached as much as 250 pounds—at which point she went on a NutriSystem diet and quickly lost about 100 pounds.

Do you think that Arian was exaggerting or being careless?  Is citing a maximum as a maximum not fair?
