Perfect Clear Study - Phase 1

[Blitz]

I think I have identifyed a parity related problem that occurs in any sequence where the following applies.
1 J piece is used in the matrix
1 L piece is used in the matrix
1 T piece is used in the matrix
7 or 8 pieces that are not L J or T.

I believe a pc cannot be done with this sequence because no matter how you play them you will either encounter parity issues or encounter the need for a second L or J piece. Not going deeper into this. I'm right untill someone can prove me wrong by posting a pc fumen where they use a sequence ccontaining 1 L piece 1 T piece 1 J piece and any other pieces.
NOTE: ONLY USE ONE L J and T. Do not use 0, do not use 2.

I just realized I only talked to caffeine about this and didn't post anything. I was studying the properties of various pieces as they affect the odd/even parity on a row-by-row basis. I imagine this is what you are approaching. In short, count the number of minos a piece in a given rotation adds to each row. All rows have to end up even. Certain pieces cannot make certain rows even if they are odd. This lends itself to a number of interesting observations, none of which I remember right now, but I see caffeine lurking the thread so maybe he'll want to go into detail

Just something I was doing out of boredom..

I certainly didn't cover them all, but I got many of the ones I've found useful.

Okay, now try a 10-11 piece sequence that has

a) bag 1.
b) pieces 8-11 have no duplicates, and no I L or T

Can one of these be made into a PC?

hmm. suppose it can, if you spin in the second z when it arrives in the second bag and hold the J.

The vertical S placement is what causes the parity after lineclear to change, to accommodate the T piece.
