Overview of the second pc

After you have completed the first perfect clear within 4 lines, such as with Perfect Clear Opener, you will be left with 4 pieces from the last bag. Using the leftovers and 6 of the 7 pieces from the next bag, you will do the perfect clear, leaving you with 1 piece. The objective of a good perfect clear setup here is to have the best possible leftover piece, with the hierachy being T > O > I > J/L > S/Z. This article is intended to be used with pure perfect clear looping and not with DPC.

How this article is organized

Each queue will make a different setup, however there are some queues that will make the same shape. This article is organized by each shape, and then the queues that can build it. Any queue that has an exclamation mark means it can't be built every single time. (Keep in mind that that is not bad; they are most likely still worth learning.) As well, if a setup does not specify the perfect clear chance it is 100%.

With a T piece

Tub

Tub is an excellent setup that is very easy to save O with. The setup intends for the "tub" to be filled in with ST/ZT and the 4x4 empty spaceto be filled with a JLZI/JLSI box.
