That is why his luck % of 104.23 after 7,292 rolls is so high.

Do we know how PD calculates the luck statistic?

I just made a new account ('dooglus2') and played 24 times at 3x (33%), noting wins, losses, and luck:

wins    losses  luck
0       0       NaN
        1       0
1               202.94
        2       101.47 *
        3       67.65
        4       50.73
        5       40.59
        6       33.82
        7       28.99
        8       25.37
        9       22.55
        10      20.29
2               40.59
3               60.88
4               81.18
5               101.47 *
        11      92.24
        12      84.56
6               101.47 *
7               118.38
        13      109.27
        14      101.47 *
        15      94.7
8               108.23
        16      101.47 *

I can't immediately come up with the formula they're using.

When I had won 1 and lost 1, my luck was 202.94%. I had bet twice at 33%, so my expected number of wins was 0.66 and my actual number of wins was 1. How do I get 202.94% from that?

Note that my #wins was exactly double my #losses 5 times (not counting the starting 0,0 case) and each time it was, my luck was 101.47%.

Edit: this fits pretty well:

    (0.6697 / 0.33) * (wins / losses)

I don't know why 0.6697 though, when my chance of losing is 0.67

Dooglus, stop wasting your time calculating obscure statistics no one cares about and re-open your dice site already.

Much love.
