Fig: Recovery 2nd PC bag structure. Last 4 pieces of Bag 2 have already been placed before you start. Includes DPC Recovery, which involves placing the extra piece in a specific spot compatible with a DPC setup.

Minimal Setups

Recovery 2nd PC setups marked with ⭐ have 100% combined build cover and 100% solve rate (or 100% recovery into Recovery DPC).
You must learn these setups in order to always be able to loop using Recovery 2nd PC following respective 1st PC setups.
Refer to the From 1st columns to see which Recovery 2nd PC setups are needed for which 1st PC setup.

Optional Setups

Included because these setups may be preferred over minimal setups in terms of simplicity/scoring/saved pieces.

Tub 2nd

Tub + Vertical I 2nd

Better saves than Tub + Horizontal I 2nd, but harder to solve.

Minimals (7)

Extra (7)

Extra Save O (7)

Rather than memorising minimals, it's easier to just solve box using a larger number of simple solves.
The last 180 minimal is the only one you need to memorise.

Tub + Vertical I has 0.24% forced save I. These queues are OSZ<I<JL<T. This solve requires 180:

Fig: Tub + Vertical I forced save I minimal 180 spin.

Forced save I can be avoided by placing O at the wall:

Sometimes it's possible to get extra Tet with 180:

🩹 Tub + Vertical I on the wrong side Recovery

If you build Tub + Vertical I on the wrong side, those 0.24% forced save I queues actually become fail queues. In that case, use this recovery:

Tub + Horizontal I 2nd

Simpler to solve than Tub + Vertical I 2nd, but worse saves.

Factory 2nd

Factory 2nd is a setup family. Factory setups vary depending on whether space divisions are connected to the central box segment or disconnected.
Factory variants with O space connected to box space can use solves that span the space division boundary. Always build one of these variants.
Factory variants with O space connected to box space can use 180 solve that makes use of the side being only 2 high.
Factory variants with T space connected to box space can use 180 solve that makes use of the side being only 3 high.

Always build variants with O space connected to box space.

Factory variants with O space connected to box space can use solves that span the space division boundary:

Factory OT (100%) 2nd

Minimals (7)

Extra (2)

Factory variants with O space connected to box space can use 180 solve that makes use of the side being only 2 high:

Factory variants with T space connected to box space can use 180 solve that makes use of the side being only 3 high:

Fig: Factory OT/TX variants-exclusive 180 spin.

All Factory variants can use this 180 to increase Tet chance:

🩹 Factory Recovery

Depending on which column you placed the first O, you will be able to go into S Recovery DPC (at the wall) or S Just be careful not to clog the holes for T and second of J/L with S/Z you dumped on top.

This recovery can also be used to avoid the forced save I minimals.

O in the middle Recovery

O at the wall Recovery

Heart + PCO 2nd

Very difficult to solve without a method.

Minimals (9)

Extra Save O (5)

Assuming you're following up with DPC, look for solves in the following order:

1. Save O Tet solves (minimals 1-2)
2. Save O JLSZ qb skims (minimal 3, extras 2-4)
3. Save O JLT qb skims (minimal 4, extras 5)
4. Save S 3x4 box annoying minimals (minimals 5-6)
5. Save S 5x4 box (minimals 7-8)
6. Save T 5x4 box (minimals 9)

Space divisions make finding solves simpler:

Box solves

Annoying minimals
