Time dereases proportional to the square root of acceleration, so if Jupiter is 6 days out
at 1G, it's ~2.5 days out at 6Gs.

I just handwaved them as limited to 5% fo lightspeed. That's about 12 days' constant
acceleration at 1G, and 2 days at 6G. For normal operations in Traveller it only affects
5G and 6G drives, as they can hit the cap inside 3.5 days and thus it reduces the
distance at which an in-system jump is faster than a 5 or 6G ship.
