It looks like I was misinformed on the level. The $50 is for full base reward on free rolls. This is a slightly different calculation. That screenshot I posted is from a virgin account (never rolled anything). So it looks like the amount is about $63 but it will be less than that because you have gained ranking by betting as well. Have a look at the link on the free rolls page and it will show you exactly what you need to do.
the new feature is pretty useful, thanks. It would be also good if users could see their total wagered amount. I know this statistic will be shown during the wagering contest, but it will probably only be for July, not the whole time
