Just add a section in your stats panel where you can see how you doing in the week for example It shows you:
kills,deaths, Money earned , Money robbed, Money Lost , bullet fired , bullet hits , vehicle destroyed etc...
If you think its useless, actually It makes sense since the fact that you can view your earnings and your losses and you can see by yourself if this week you made a profit or you lose Money.
Also you can figure out how many kills you did and a lot of more informations.
Of course make It possible to view only for the current week or the last week and the current week.
For example:
/stats -> your player stats -> Weekly Balance -> Current week or Last week
