Second Perfect Clear

Overview of Second PC
To solve 1st PC, you must take 3 pieces out of the 2nd bag. There will then be four leftover pieces, which are usually used in the setup. Since you use six out of the seven pieces out of the new bag to solve 2nd PC, the unused piece is referred to as the "saved piece," and will be the 3rd PC/DPC you go to. Usually, good setups will depend on whether you are DPC looping (O > SZ > I > JL > T) or doing pure PC (T > O > I > JL > SZ). This page is designed for pure PC. '''If a setup has an exclamation mark after it (!), that means it cannot always be built with any queue. Usually, there will be a different setup that can be built instead, but again, no guarantees are given.'''

How this article is organized
Each four-piece queue can make multiple setups, and each setup can cover multiple queues. This page shows useful setups that usually cover multiple queues in order to be as efficient as possible. Some queues may not be covered, and other, more specific setups might be needed. These setups may not be exactly the best setups for specific queues, as some compromises are made in order to make sure this page is not too long.

ILOT/IJOT
''100%, 100% no save S/Z, 97.66% save O/T Note: If this setup seems too hard, this queue can also build Heart + PCO, which is easier at the cost of slightly worse save chances.''

Queue based setups
Queue based setups are dependent on the pieces from the next bag, meaning they are not totally consistent. However, seeing a piece coming early could bump a setup from nail biter to guaranteed save T. While queue bases setups are much, much more extensive, this article will only go into the ones you really should know.

IOSZ, early J/L
Much, much better then IOSZ normally. The setup will need to be mirrored depending on whether you see J or L.

''Note: This setup is done with the I piece held. However, since you can see 6 of the 7 pieces in the next bag, you can deduce what the last piece is depending on the piece you do not see.''

IOZT/IOST, JLST/JLZT early Z piece
This is an easy 1 solve setup that is guaranteed to save O. This can be also mirrored for early S piece.

Solutions:

IJLO, early S
One mininal with save T, absolutely good to learn.

Solutions:

JLOZ early S
Another great 1-solve guranteed save T.

Solutions:

IOSZ early I
Another easy save T.

Solutions:

IJLO early LZ
Quadruple box! This queuebased also covers all non-save T setup for the normal ILJO setup.
