The couple enforced the new strategy, relying on more specific restrictions to deal with the random encounters during the flight. As Khan had predicted, they became more frequent, inevitably delaying the journey as he addressed each of them.
Taking care of each pirate ship stole valuable hours from the flight. Khan didn't only need to stop the vehicles he encountered. He also had to board them, force the crews to drink the restrictions, and remain nearby to check whether they followed his orders.
Time wouldn't necessarily be an issue in other places, but the flight route grew more populated by the day, and each ship forced Khan to stay still for a while. That increased the chances of someone spotting him while he was busy taking care of other crews, causing countless complications.
