The cut off is Saturday at 11:59PM----Sunday at 12:00AM the counter resets it may take a day or two for your total completed to update but you will know it's there by looking at your total unpaid searches in the dashboard. Just click view statement.
Also remember once you hit payme now your statement resets so then you won't see your searches there after you pay yourself.
Here's two tricks I always do:
1. Get a sheet of paper and hash mark all of the searches you completed everytime you do one mark it down so you have a personal verifiable record of your total. (I also put the time and date of each of my sessions)
2. If you use the payme now and have a ChaCha card then use the firstib bank statement to calculate how much you've been paid to figure out your total don't forget about them $2.00 charges to use that feature as well.
Hope that helped.

I only did $40 this weekend...been slackin'
