I don't really understand what you are saying here....
Pride of Labor and Piece by Piece are the same thing.... One is for decorations and one is for parts.
They both, if succeed, will advance the synth like a rapid, but each has better success if you are synthing what it is good for. They defiantly don't stack.
Using Ingenuity with either of these makes no sense either... I would rather just carefull synth when Ingenuity is active.
The only way to increase the chance of the 30 progress abilities working is using the one that corresponds with the synth you are doing, or using then when the orb is unstable/chatoic.
Assemble - Finished (should be used the most)
Mass Production - (more then 1 yeild, etc ingots/leather/cloth)
Grand Design - (materials)
Pride of Labor - (finished items, there is so few)
Piece by Piece - (parts)
