Why does my Admission Chance seem to be unusually high for Northeastern University?

Answered

CollegeVine says I have an 89%-92% chance of being admitted to Northeastern University, which has a 19% acceptance rate, while other schools on my list have admission chances that seem accurate. It says Duke and Northwestern are long reach schools, with a 5%-15% chance of being admitted (both have a less than 10% acceptance rate), and schools like UMich and Georgia Tech are target schools, with an 80%-84% chance of being admitted (UMich has 40% acceptance rate for in-state students (23% overall), GT has 22% acceptance rate). Those four schools' chances seem reasonable, so why is my chance for Northeastern so unusually high? Some background info, I'm a white female from Michigan, my extracurriculars are pretty good, I have an SAT score in the 99th percentile, a 4.0 unweighted GPA, and I plan on studying mechanical engineering.
