Did a quick spreadsheet, the rate of increase is between 6.5% to 5.1% for each individual year from 2003-2014. A special >10% increase in 2008/09. Seems to decelerated recently in 2014 and 2015 to below 5%. Last increase is 3.1% (or 2.06% if u considered the period is 1.5 yrs instead of 1yr).
But I guess nobody can tell the future rate of increase of FRS.
well, already written in black and white that it is 3% till 2020, i.e. 181k. At least u can be sure there is no sudden increase within these 4 years
