For progressive to work, it has to have a lazy slope in the beginning of travel, otherwise, it's not progressive. Linear response means you push it halfway, you get half of what you are supposed to get, faster response, etc. I get the exact opposite feel that you describe, in sport/comfort it feels dead to me unless I push it nearly all the way down. In track, it response better in the mid-travel. This is probably to make it more "driveable" in sport/comfort, so you aren't breaking traction all the time.

Track throttle map is linear. Sport is supposed to be also when you read the magazine article where Randy Pobst talks about telling the GM engineers it was hard to control the throttle when at the limit. He talked about how the throttle mapping used to be aggressive at the low end and dead at the top. In RC we would call that positive exponential, you get more throttle output % at lower throttle input %. This makes the car feel quicker/more responsive with less throttle input. But it also makes it harder to manage the throttle when at the limit. I can feel that in my car, Tour has more aggressive throttle mapping than Track. I haven't driven in sport enough to see if there is a difference.
