Well so far my calculations with regards to number of points per day is correct plus or minus a few ponts ,it stands at an average of 333 points per day.so it will take around 18 days to reach level 7.
Would be interested in the points per hour, as I put in a little time first thing in the morning, and then last things at night. I'm at level 6 and that is fine. Don't want to live on here.
