I began the game from exactly 6 weeks and i spent 40k scouting since I began.. also to confirm this, I have now six 40k scouting bills in finances department.
Results are: 20 players scouted once and 9 scouted twice = 20 +9x2 = 38 scoutings.. since i spent six weeks 40k, then i paid for 4x6=24 scoutings.. which means I had 14 for free ;)
