I was able to complete an Ocellus station solo in about 35 hours of playing time. I used a Cutter and no Fleet carrier. So this is doable even for a large station. The CMM increase really made it better. I think it would be reasonable to extend the time to complete the first station to 5 or 6 weeks for CMDRs who have limited time to play. Overall though I really like the Colonization feature. I'm not sure I like the capped system income though.
