Hello,
For me there is a huge mistake in the calculation of the winning chances :
Chance calculation to hit a block in solo mining using different hashrate examples:
at 1 PH/s --> 1 in 267.342 per block or 1 in 1.857 per 24h
at 2.5 PH/s --> 1 in 106,937 per block or 1 in 743 per 24h
at 5 PH/s --> 1 in 53,468 per block or 1 in 371 per 24h
at 10 PH/s --> 1 in 26,734 per block or 1 in 186 per 24h
at 25 PH/s --> 1 in 10,694 per block or 1 in 74 per 24h
at 50 PH/s --> 1 in 5,347 per block or 1 in 37 per 24h
You can't say for example that there are 144 blocks mined each 24h (=1 each 10 min) and thus if we run the miner 24h non-stop we multiply our chances by 144.
Yet this is the reasonning applied as for example : with a hash rate of 50 PH/s --> chance per block = 1/5347 --> chance per 24h = 144/5347 = 1/37 which is false.
Since the draws are independent for mining each new block, the chances are constant as long as the hash rate is constant and no matter how many times you repeat the mining tentatives.
There is a topic in wikipedia that gives a better explanation :
