Yeah, I think it's important to remember the POINT of motorpacing, and to plan the workout accordingly.
Somebody working on WINNING races is going to want to pace behind the motor and then sprint around it; somebody working on SURVIVING races is just going to want to be paced at higher-than-comfortable speeds and do some hang-on windups.
A former teammate of mine preferred to motorpace at moderate speeds in a moderate gear to work on legspeed; I found that strange, but it worked for him. I preferred to motorpace at high speeds (55kph), occasional sprints + chase back on, and windups to finish each motorpaced interval. It did a great job of race simulation that was harder than races I was doing; 3x 50-lap sessions was a pretty tough workout.
