Not that I am aware of Sean. When I used to check that, I had to go to my account section and add up all the winnings and take out all the entries.
The total earnings stat is a somewhat of a farce, as are a bunch of the stats on here.
Par for the course I suppose.
If there is another place with the net, I don't know about it.
EDIT: I guess if you look at your bank you should know. If you started with 5k credits a few days ago and have more now, then I would suppose you are earning credits. Unless, of course, you have outstanding RGs to pay out
Oh, then you have ball use, so forget it, that doesn't work either
