@Jagra You have to somehow identify the piece in your function you want to extract. You did this by indicating position of it inside Piecewise, but were apparently unsatisfied because that was fragile. I agree. But to have it not fragile, the only option I see is to use conditions for this, at least if you want to do this programmatically.
