Third perfect clear

Overview of Third PC
After completing the second Perfect Clear, you will be left with one piece. Here, the perfect clears get much more abstract. Instead of having 1 rigid setup for each PC queue, you will have to assess the queue ahead and make a decision. After solving your third perfect clear, you will be left with 5 pieces, for your fifth. How good setups can range wildly, from getting a 100% setup almost every time with a T piece, to being lucky to have a good setup at all with the S/Z piece. The order of good saves is (T > O > I > J/L > S/Z)

''Note: Extra O and Extra I 3rd is a pretty hotly debated subject. While theoretically Extra I can be better, Extra O is much easier and safer to do''

How this article is organized
This article will be organized by the pieces, from best to worst. The article will cover some notable best-chance field setups, as well as a "main" setup to fall back on.

Note: Try not to rely on this too much, as the 10% chance of failure is still there.

Main route
Note: Creates the same shape as Extra O main route, so carries the same percentage.
