The odds
At that day's difficulty, a rig this size expected one block every 500 years — about 1 in 180,000 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. Odds like these are why solo mining is a lottery, not a paycheck. Run the same math for your own hardware on the odds calculator.
