Here is an update a week later. We have decided to break down the stats into 2 set of stats: newly polled users (polled since the last results) and total (including the previous figures). Ideally looking at just the newly polled users would give you the right results but since our pool is small, we figured providing both would make sense.

Here they are

New Users:
14 Oranges iOS Statistics New Users Mar 2012

14 Oranges iOS Statistics Total Users Mar 2012

As you can see, 5.1 is increasing. Note we had a bit of a spike with 4.3 users but likely due to our small sample pool.
