All you can do is to keep all wires as short as possible, and make the
layout of the parts resemble the schematic layout, unless that is
obviously wrong.

During troubleshooting in test lab, it is tempting to be quick and
connect filter solutions with soldering and some wires.
Instead, you should probably lay out components on a pcb and get it as
it is described in the books. But in practice, at the test lab, you
can't do that and the question is how messy can such an EMI filter be?
How long can the wires between CM chokes, capacitors be and when you
don't solder but use Wago-connectors for interconnection, is it so
that the filter is almost already destroyed by the impedance that you
have no control over?
As we get up in frequency (conducted emission 150kH-30MHz), messy
design / connection will get more worse when frequency increase, but
we will get trouble anyway in the 150kH-30MHz range. At least from
1MHz. Right?
