I’ve gone through this process before and while it was more work it did not take 30 minutes.
I presented a student ID and was escorted through the security line. My baggage was selected for additional screening and I received a pat down search.
I went through an identical procedure on the return flight, right down to the exact words the TSA agent spoke to me while conducting the pat down.
I've also gone through this process, it did take about 30 minutes in my case. That also included waiting for a TSA agent to be available to even start the process. So YMMV, perhaps based on how busy the airport is at the time.
They had me answer a series of questions about past addresses etc, it wasn't just an extra pat down in my case. After answering all the questions correctly they allowed me to continue.
