I'm flying out of there every other week and by and large I'm under 5 minutes to get through pre-check lines. For non pre, that's where the lines can be 5 min or an hour. For Friday afternoon, it's not peak travel but if you happen to be there when a large foreign tour group is going through that's where it can suck as TSA is only reactionary but again I think it's safe to say most of them don't have pre. I think clear is worthless but at least at MCO they have two lines (one of you have pre and one of you don't) so you can skip two people in line if you want.
