OK, so I took a stab at your "hack" below. Here's what I got...
On the "Stats" page, under "Normal View", your hack works as you mentioned.
However, when I move over to "Single field view" on the same Stats page, it does not give the money total - it shows that same person as having won $0.00. So I double click on the individuals name to get his individual statistics, and it does show an adjustment for the correct amount. But, for whatever reason, it will not show this amount under the "Single field view".
