Why is there such a big difference in sample rates year on year
I'm seeing single figure sample rates for date ranges of a month in 2015 but when I look at the same range in 2014 the sample rates are usually more than double. Why?
Also, in the same vein, If I use the 'compare to: previous year' feature an increase year on year viewed in separate tabs becomes a significant decrease. How is that right?

sampling in Analytics occurs if the number of sessions in a report exceeds about 500.000  - so, most probably, your number of visits in 2015 has doubled compared to 2014.
