```Hi Max,

yes I mean EMG. To clarify the argument:

suppose you are playing a 8 point match. In the first game your are
really unlucky in terms of EMG, but because the cube isn't turned you
end up loosing just three points. In the second game you are a bit
less lucky in terms of EMG (compared to the bad luck in the first
game), but now the cube is turned to 8 and you end up winning 8 points
for the match. Now your EMG luck is negative for the match, but your
match equity luck could be very positive.

I suppose that you should consider your self lucky for the match, and
therefore prefer the match equity numbers. However, I like to have the
numbers the way they are to keep them comparable to the error rates.

Christian.
