Interplanetary travel times

I just came across this stack exchange post (http://space.stackexchange.com/questions/840/how-fast-will-1g-get-you-there) discussing travel times between planets at 1 g. According to the post, travel to Jupiter would take about 16 days. However, in the books, it takes them weeks. Why is this? Am I missing something? In the post, they use the closest distances to Earth. Is the farthest distant significantly farther?

You gotta stop, half the time you will be accelerating, half the time you will be decelerating. My guess it takes less time to stop since fuel and expendables (air, water, food) may be consumed, hence less mass to stop (f=ma).

Also, only Earther ships would normally travel at 1G. It would be torture for Naomi.

At it's furthest point, Jupiter is nearly twice as far as at it's closest.

Dramatic licecse!

All travel times in the expanse are exxaberated by ~10x. Or, more realistically the acceleration described is 10 times to high. The ships would also not be able to sustain the accelerations described as long as described even with a 100% efficient fusion drive.

Real interplanetary travel with an "Epstein drive" would probably happen at a lazy 0.1g (1 m/s^2)  where the Expanse puts it at 1g (10 m/s^2). Simply because of the fuel economics in play.
