Also, when I compute the daily dividends for MINE using the info from the Bitcoin wiki, I obtain a value that is 2 satoshis per day per share higher than what has been paid out to MINE. This discrepancy could be a rounding error, but those typically shouldn't exceed 1 unit at the smallest denomination. Could you specify which equation you use to compute MINE dividends?
I got the same div as twentyseventy with the formula from the OP:
5000000000 * 25 * 86400 * (65535/2^48) / 2,193,847,870 = 0.00114617
Which formula do you use?
