    These numbers are derived using the daily percentages and sample size for five days going back from the listed day on each line.  The total sample size ends up being around 1800, which should have a margin of error below the 3% for the three day rounded numbers (2.3% if the formula I was given is correct).  The earliest numbers will be slightly stale, but this five day average helps to show more general trend movements by smoothing out noise present in shorter samplings.
