Got 2 days last time from memory, making 12-15 times that profit this time. Formula was last revised to kick in earlier but reduce as profits increased. Therefore max would be 30, min 24ish days, around 3 weeks (since profit share tapers) from analysts estimates of profits. The more we make the less we get, as a ratio, though the amount still increases.
Rumour of a new formula this year, so who knows.............
