Help me out here. The green line is the cumulative Cd not counting but not ignoring the downstream effects?

The tractor's contribution is 0.095 because it is being drafted by the trailer?

The taper in the rear causes an 80-90 count increase in drag?

I suspect I'm missing something. Or just totally wrong.
