Turnitin February model update, what actually changed

A lot has changed since the last time anyone reviewed this properly so I figured it was time for a fresh look.\n\nQuick summary for those who do not want to read the whole thing – it is better than most alternatives but not perfect. There are specific situations where it shines and others where you should look elsewhere.\n\nNow for the details. I tested with 10 different text samples of varying lengths and styles.\n\nCurious to hear from both students and teachers on this one.
