Total practice turnover (Figure 1) reveals the high point over the two years January 2009 to January 2011 as May and June last year at 174 Index points. With the exception of January and December 2010 (the months affected by adverse weather conditions), the values remained higher than throughout 2009. The moving average (which includes the historic values over 12 months) shows a steady incline from February 2010, levelling off after October 2010.
