Hi Amund/Gert,
I agree with Gert’s advice, that all (especially high speed) signal layers need
to have an adjacent ground return plane in order to properly capture the
electromagnetic wave of the digital signals (which travel in the dielectric
space between layers). The one exception, in my
It s an extra layer you might allocate to that low frequency signals ,
analog signals and or extra power supply.

Just one immediately follow-up ==>This Misc layer, is it an extra layer for
signal routing, as a Sbott3?

Just 2 hints of thousands:
If you implement 2 ground planes make sure the ground references on top
and bottom are related to the closest ground layer .
The stack will than be: Stop -- GND --Stop2 -- PWR - Misc - Sbott2 -
GND -Sbott ((S=signal))
(basically you route 2 x 3 layer boards
Look for books and other publications by Keith Armstrong, and others by
Tim Williams.
