Possibly the training dept at mesa sucks big time(so i've heard) don't know much about TSA training dept. Overall it doesn't really matter how long it takes as long as the product at the end of OE is a safe competent pilot. A guy I know had an engine failure his first flight and the way he handled it made it clear to the captain that he was ready for the line after a 4 day. My first approach was a CAT 2 down to mins. Talk about pucker factor.
