    At 100,000 pilots with decent exploration ships, that's 4 million stars apiece. If you estimate 30 seconds per system, which gives enough time to scoop fuel, pop off the advanced scanner and align to your next system, it's 33,333 hours per person, or 3.81 YEARS, not counting travel time to get to each pilots 4 million star sector.
