The inseam is ground to groin, and the trunk measurement is roughly groin to sternal notch. So when you add the inseam and the trunk measurement, it should be roughly the same as the sternal notch measurement. That being said hers is way off. remeasure, and be sure to watch the instructional video.
I'm 6', and my trunk is a hair under 25".
