RE: How to effectively use the Explorer II in NextColony

Great article and approach to the hourly efficiency compared to the explorer 1. The problem I see is that the chance of getting lost still far outweighs the chance of finding a planet with the Explorer II in the 60-70 tile range., but that can be limited by going on much longer runs (say 200-400). At what range does the overall resource cost of losing ships outweigh the time burden of making new ships to explore?
