I sincerely hope it is the majority of the field, but since scoring is so concentrated in the "elite" tier it is possible for maybe the top 20% or less to drag the event average up by themselves.
There are several factors at work here. Certainly practice and play time will make anyone better, and teams have a chance to make changes and improvements to the robot over the course of the competition. But good teams automatically give themselves room for improvement.

A team whose robot has a fundamentally flawed mechanism that never works is not going to see much improvement over the event, because no matter how good their drivers get, the mechanism is their limitation. A better team that is working on accuracy might have more success as their drivers improve their aim. A great team who has good accuracy will improve as their drivers get faster and can make more shots.

The tricky part is that you're inherently focusing on offensive capabilities that scale. A robot who is only designed to play defense and hang for 10pts this year won't see any "improvement" in this scheme, even if their mechanism works perfectly, because they can only score 10pts maximum ever. Their defense may improve drastically over the course of the event, or how quickly they hang, but we don't have an accurate way to statistically evaluate that.
