It had been half a year since the Hope had left that part of space, and within that half year, the Hope had only warped twice…
Yes, with the Hope’s upgraded energy circuits and the ample energy provided by the polymerized reactors, the Hope could warp at least 10 times every 24 hours.
However, those kinds of warps were completely random; they couldn’t be controlled. And in comparison, the two most recent warps were "controlled" warps. In other words, this meant that the Hope knew the location it was warping to, and the exit they would end up at wouldn’t be more than 10 light years away from their intended target coordination.
