To me, the current payment process period is fair enough, and should give google the time to filter those invalid clicks.
the payment process is quite fast and satisfactory becuase its understood that some time is taken to monitor clicks.
Why not think that Google sends payments after 27th and look into the Payment Page only after 27th every month for the correct update.
Well, we all wish its faster. However, we just have to follow their conditions. However, if you have been blogging for more than 2 years, you will find it faster as you most probably would be earning $100 monthly by then.
that is fair enough i guess. google need to check all validity of the clicks. one week is not enough...
