I'm not sure you're thinking about those terms in the right way.  "CG Leverage", whatever that means, is not a characteristic of a particular core but more likely a layout that can be used when drilling the ball.  Likewise for "CG out leverage".  Are you curious about specific balls you have?

I would guess that "CG leverage" means the pin is 3 3/8" from the PAP (leverage) with the CG also 3 3/8" from PAP.  Usually it's called "stacked leverage" and is considered the "most" hook, for some definition of "most".

"CG out leverage" probably has the pin in the leverage positions, 3 3/8" from PAP while the CG is less than 3 3/8" from PAP, it's kicked away from the grip center towards the PAP.  This type of drill usually gives a more controlled, continuous hook than stacked leverage.
