My sales seem "normal" to be honest, but my sales tend to come in fits and starts, anyway, so it can be hard to guage.
Even on my main account that does most of my activity, there are often 2-3 day gaps with no sales but then some days I'll have 10 in a day, often in a few hours and with many in the same area (the cassini syndrome in full effect!)
The monthly averages tend to be fairly consistent, but the way it comes in over the month can vary wildly.
So for that reason, it's always hard for me to judge any immediate impact on sales.
One thing I did notice is that of the 3 days where my impressions reporting was iffy, 2 of them have now risen up retroactively, the 3 days are still below what has been average for the last few months, but have gotten closer.
1 day in particular was about 50% of average impressions and then 3 days later suddenly rose up to about 80%
