In the Japanese demo, 25% pressure = 50% throttle; 75% pressure = full throttle.
In the full retail, Spec II, 25% pressure = 25% throttle; 50% pressure=50% throttle, and around 60% throttle/60% pressure, the throttle suddenly starts to become more sensitive, and by 75% pressure you're at full throttle.
Yeah, the end result is the same: 75% pressure = 100% throttle, but if I've explained this sufficiently, you'll understand that it's the strange changes in sensitivity throughout the range of motion that set the two versions apart.
Edit - June 1st: I'd also like to show you all the comparison video I just made, which shows how the throttle responds differently in the 3 PS3 GT games.
