I'm up to 20 for the month but not without major frustration. I am getting into more surveys but getting kicked out after completing more than half of the survey. My DH also had one that got to 100% completed and then when he clicked on the next page button it dropped back down to 30% completed and asked him more questions.
The one positive is it seems like the 24 hour limit is now running on a daily schedule as opposed to 24 hours from your last survey. I have been able to access surveys this month several hours before the 24 hour limit on my last survey.
