They affect the loss/gain from each exchange. If I have an edge of +2, and I
stake 10, I will gain 12 on a win, and lose 10 on a loss. An edge to me is the
same as a handicap to you, the only difference being persistance (ie. if I move
on to someone else, I usually take the edge with me, depending on why I have
it).
