funky...
it seems to me that lot of people posting on rupnet, probably close to 50%, have a dependent also in 485 stage (derivative) - either a spouse or a child. if that's the case, then even conservatively, each case on rupnet, usually, could amount to two approvals. however, that also hikes up the number of posters to twice, and percentagewise, things don't move. so yes, we'd need about 6 approvals per day (of course, considering everone diligently posts and doesn't forget password, or isn't naturally overcome by ecstasy or freedom-bells still ringing from the torn shackles) to keep things from getting non-linear. but, on the positive side, rupnet is actually 1% of the total cases filed (instead of just 0.5%) - so that has to be a big deal!
