Good point: I didn't check where the setups came in.
perfectclear: for the sake of sanity and the fact that players aren't in this to prolong the test, I would judge that a setup is complete if and only if the entire thing is built with no other intervening setups. That means that you wouldn't build most of a C-spin, take 10 other clears, and then get a TSD that is in the "same place" as the C-spin and call it a C-spin. The goal is to show that you can produce by-the-book setups, not that you can be super creative with their knockdown.
As stated previously, the intent is to not screw you over if you get bad pieces--but you still have to build the shape. I think you're overthinking it a little - this isn't a puzzle to solve, just a demonstration of knowledge
(And to head off the followup to this: Paul: I think we should stipulate that the setup must be knocked down one way or another. Every line that participates in it should be cleared. In this way, we don't have people trying to shortcut the system by restarting early, etc.)
