Oh crap... this is how it actually goes:
X / Sqrt(Y)
= (X*Sqrt(Y)) / Y
which puts us back to square 1... on why doesn't it work, or works like that even when using sqrt? I have tried decreasing, but also increasing the G_FORCE to compensate lack of particle density in depth direction. But at the same time there is a more uniform force pulling every direction, from the overall system.
