размышления на Reddit по поводу изменения "distance from port"

So after /u/warp99 comment bellow I decided to see what would cause a 50 mile sorter landing spot via flightclub. There are 2 possible explanations.
1) Lower MECO velocity: This makes the most sense. With a lower MECO velocity flight club points out about a 20% increase in S1 propellant (~5 tons of propellant) compered to other GTO landing attempts. This would mean higher chances of a successful S1 return and/or less damage to the stage.
2) Higher S1 apogee: Oddly enough, it was hard to get a trajectory that would put S1 at 600Km. Here you see a apogee of 150Km which still doesn't bring it to closer west towards the barge. The problem with this profile is it increases vertical velocity and reduces horizontal velocity. Which isn't very optimal for GTO launches.
P.S. I just modeled S1 trajectories. I didn't spend time on the second stage. Maybe i'll update that later.

по-немножечку портится прогноз:
