Thanks for the explanation.
For the sake of clarity, since the significant figure is the one in MWC,
I would put the EMG lucks in brackets (right now the MWC lucks are in
brackets). Swapping the two should have no impact on menoy sessions,
since for money the two are equal (equities).

Also, the label "Luck rate (total)" followed by something like
"-0.920 ( -5.335%)" is misleading: it looks like that "( -5.335%)"
is the "(total)" ...

What about this:

Luck rate, total (EMG)                    +16,885% (-0,068)    -13,908% (+0,178)  
Luck rate, per move (EMG)                  +0,241% (-1,0)       -0,196% (+2,5)  

For money it would be smoething like:

Luck rate, total (EMG)                    -0,068 (-0,068)    +0,178 (+0,178)  
Luck rate, per move (EMG)                  -1,0 (-1,0)       +2,5 (+2,5)  

MaX.
