pretty dumb scribbling.

e.g. in "126,000 km/h)" the 000s are perfectly meaningless, a less stupid way to put it would be "126 Mm/h"
and, of course, km/s would be much more reasonable units here, thus "35 km/s"

sothe boost is from 35 to 38.9 km/s , delta-v of 3.9 km/s and this is "70 percent of the initial boost.." ???
if 3.8 km/s is 70%, 100% = 5.5 km/s -- where did the 35 km/s come from ?

What this shows is how difficult it is to get to the outer planets with current rockets that spacecraft have to use Gravity Assist Trajectories to get them to the right place. I have done some of the number crunching involved and it is a lot of work given that they can get the craft to their destinations so accurately. Which does make such a thing so impressive.
