Based on what? You literally just made up 2 times.
She gets better as the distance gets higher. 52.75 400h > 50.07 400m > 22.37 200m > 11.07w 100m. And you have to have more strength for the 400h than you do the 400m flat obviously. She's ran 2 54.xx 400h's this year (prelims for SEC and NCAA's) and she's looked completely effortless. The top 800m girls in the NCAA run 54 in the open without hurdles and don't look effortless. She just has talent, plain and simple. Give her 3 months of 800m training, she could be competitive. Not on a world stage, but certainly on a collegiate level.
