Incorrect reasoning ... due to the serial nature of segments of a trajectory.
Think of it as a relay race. Each runner completes a segment of the total race. Only one person can run at a time, whether they're running at 100% or at 10%. Nobody can run leg 2 until the runner on leg 1 can pass the baton to the next runner.
Adding a slow runner to the team SLOWS DOWN the ability of the team to win the race. The slow runner's effort is useless until he can pass the baton to the next runner.
