No hour has been drawn yet. When the first one closes, two drops are drawn and split everything the other drops put in.
Twelve drops make a 60,000 hopper. The draw block's hash lands on capsules #4 and #9.
Each takes 30,000: its own 5,000 back plus 25,000 from the other ten. The ten other drops paid them; the next hour opens in the same block.
With three drops in, a drawn capsule takes 7,500 for its 5,000. With forty, 100,000.
