Hi Michael, I would say that you are definitely on the right track.
If you are certain that there is no air in the system then my guess is that
you are struggling with " compressability " of the clutch disc.
They are designed that way to "soften " engagement.
A slightly larger diameter master or smaller diameter slave should resolve
the issue but remember that you are dealing with area here so the change in
displaced volume is the square of the diameter change.
