The odds
At that day's difficulty, a rig this size expected one block every 75 years — about 1 in 27,000 on any given day.
That is the one formula behind every odds line in the record: the network difficulty at that height, times 2³², divided by the reported hashrate — the expected time between blocks for that rig.
