by my calcs (looking at the way the math is set up, and based on the fact that thrust 4 and 5 are the same for these entries), the transit times are incorrect for Thrust 3 and 4 for distances 600,000,000km and greater.
the correct numbers should be:
Thrust 3:
78.6 hours
96.2 hours
4.2 days
Thrust 4:
68.0 Hours
83.4 Hours
3.7 Days
