                Jagau, there are no gaps in my ZPM. My coils are mounted in the middle of each U piece of the Metglas:

and your coils are mounted over the two places where the Metglas is cut.
I suppose the places where the coils are mounted on core don't matter. But if they matter then there is a difference between my configuration and your configuration.
Just to clarify, this is where my coils are mounted on the core:

And this is where your coils are mounted on the core:

As I said at this moment I have no data showing that the position of the coils on the core matters. Why do you think the positions matters, do you have any data indicating this ?
EDIT: could be a misunderstanding, let me clarify - by gaps I mean air-gaps, the spaces between the two U pieces of the core (the places where the core is cut as indicated by red arrows in the image below):

So yes this is a difference between my configuration and your configuration, If you think it matters then you could try to place the coils in the same positions like I did. I know it is difficult to place coil supports there, I needed to order to CNC pieces which could be put in place and when glued compose the supports.
This is a hand-made design I've made to explain to the CNC guy what exactly I want:

As a note: I've made these coil supports when I was trying to replicate Bearden's MEG so I wanted to place the coils on the core exactly as it's specified in the MEG schema.
