Range for CG depth is somewhere similar to CG distance. If you remember Grandista, uses a 1:1 ratio of CG distance vs CG depth. Which is believed to provide optimal stability.
As for CG height, This varies quite a bit.
You need to look at CG height 2 divided by the total face height which will give you a percentage of low spin impact zone. Most heads stand around 35% to about 50%
Cobra King LTD pro I believe had a whopping 51.9% where the low spin impact zone (upper face ) was larger than the high spin zone.
While the trend at one point was to produce lowest spin as possible, recent JDMs have actually been moderately higher spin compared to USDM going for more stability vs ultimate occasional distance.
Based on these CG specs alone, USDM drivers generally have the potential to produce lower spin super long distance shots once in a while whereas JDM drivers can produce moderate spin but more consistent distance. For me, that seems to be true most of the time but not always.
I mean the head is only part of the solution, right... then you got hundreds of shaft options that affect the shot characteristics... You could have a shaft that can counteract the head design or maximize the
desired effects. But the biggest variable and the most inconsistent one at that is , by far , the player themselves. Swing path, AoA, SS, Face Angle are all part of the equation.
