I have been working hard trying to make a route which takes the natural portal to Umgah, which would save ~20 seconds if timed perfectly, maybe a bit less if you have to wait a short time for IGT to pass. I have tried many things, rerouting Thraddash before Umgah, doing Umgah after Supox and Utwig consistently by going into systems to encounter them, which loses a bit of time but is also less luck based, but nothing seems to line up.

Things to keep in mind while theorizing routes: Supox/Utwig must be done near the end of the run, after Thraddash, Druuge and Pkunk. Orz has to be done before Umgah, but it saves time to do it right after one of the trips to Betelgeuse. Umgah fight can be done at any time before adding the bomb to the ship, but it must be done after getting the necessary ships. There is potential to make the natural portal while using Earthling route, but would make the run much harder/luck based/slower anyway. To free the Chmmr, you must get the Sun Device, which takes a lot of steps, and probably cannot be routed any earlier in the run, so potentially routing Syreen after Umgah is not doable unless you are using Earthling route. You probably cannot route Pkunk or Druuge later, because you need the fuel refill from both sources, not to mention Ultron pieces. Obviously you cannot route Arilou later because you need Quasispace to save a lot of time and fuel.

Please respond to this forum post if you have any ideas.
