Question - how much of a time penalty is there for being in the blue zone the entire trip vs full-throttle until 6 seconds? Let's use an extreme example like Hutton Orbital. If we're only talking a few minutes for a long trip like this, then I have use for SC Assist. If we're talking a serious time differential, then I might throw it onto my exploration ship (I've got the spare slots) but not use it much at all.
It really depends upon the nature of the system, and how the planets are aligned, to be honest. Some systems you don't have much mass between you and your destination, so you don't save much time. Others might have a
lot of mass, both visible and not, so the time you save by flying manually can really add up.
For example, on one Rares CG I participated in, it turned out that there was someone I was able to be instanced with that was running the same route I was (not too surprising, there.) I passed him three times in the hour I was playing. The first time I passed him, he was already halfway to the station of the third hop when I passed him in my Python. Second time I passed him was on the second hop. He was approaching the outpost ahead of me when I passed him during my braking maneuver. By the time he
actually arrived at the outpost, I'd docked, sold my "outbound" cargo, gotten the CG rare, topped off my cargo hold for the third hop, and was already spooling up for my jump out. The third time I passed him was at the CG system itself. Given that there was combat oriented ship in his immediate vicinity, I
really hope he wasn't interdicted while taking the straight and slow route.
Kind of reminded me of this:
As for Hutton Orbital... I really don't know. My instinct is that the amount of time you could save by keeping the throttle at 100% isn't as much as the time you could save by not flying to the station directly, and not selecting your destination until you're in the immediate vicinity. Personally, I'd never want to test it out.
