Weight transfer to front foot?

After the load how much weight should be transferred onto/into the front foot? I know with some hitters their back foot comes up as they transfer weight.

Babe Ruth Says:Swing hitting depends entirely on balance and timing. Note that my weight is on my left foot. As I start swinging my weight shifts to my right foot at the time of contact with the ball. The force of the swing makes a perfect follow through.

I am not sure this is a teaching thing it just happens, I would guess 80% on the front foot.
