I have Elite explorer rank. That was dead easy and only took a week. I'm doing combat at the moment, and I've just about reached Dangerous with 2000 kills, which took about 10 days, so hopefully another 25 days to reach Elite again. Trade rank is going to be a big problem with only 6T capacity or less if I have to go more than one jump. If I could make a million per trip, that's still 1000 trips, but there's no commodities that would pay a million anyway. Also, it's too easy to get killed in a Sidewinder, so you can't do much that's going to get ships coming after you. For any passenger missions, i'd need a fuel scoop, which will take me down to 4 passengers. Do they do missions for that few?
