In-system Space flight mechanics in the Union/Alliance universe

I am having trouble understanding the in-system space flight mechanics in the Union/Alliance universe.

It seems that the spaceships come from Jump at a moderate high fraction of lightspeed, which they get rid of via "dumps". They then use their main engines to do the rest of the work. So far, so good.

Unless I am very much mistaken, the ships do not have any compensation for acceleration, so they are restricted to a few tens of m/s^2.

So, the velocities the ships can reach in a few hours or days are quite limited - around 0.6% of lightspeed in two days for 10 m/s^2, reaching around 1 AU from a dead stop. Yet, the stories seem to indicate that events happen much faster than that.

Am I missing something here? Or did Cherryh play loose with her internal physics?
