Like @Spaceman-FXL5, I normally expect to get close to or over 6 trips per hour in a hauling CG, sticking to orbital stations. I've not tried it for this particular CG though.I get 4+ trips per hour for CMM in a T9, netting north of 160Mcr/hr (better than Inara prediction). It only drops a bit when I shame loop, get interdicted, fall asleep, etc.
I've yet to master fast planetary approaches, though I really do wish I could do 'em. The punishment of failed approaches has so far discouraged me from practising them too muchIf you know how to do a fast supercruise approach [1], then a low-gravity planet is barely any slower than an orbital to get into the station instance, quicker to land than messing about with the mailslot or waiting for the NPC to clear the one medium pad, and as you say SCO can clear an obstructed jump in seconds anyway.
(I harbour a suspicion that most ED players are in the same boat as me on this front.)
