Averages

create tables

The average dates produced on the next page are drawn
from a live database of nearly 2 million records

  • Information is constantly being submitted by our recorders
    and reviewed by experts. 
       
  • Averages taken 'during' a season/year, when records
    are still being entered, should not be compared to
    averages of previous years, as data for the current season/year
    will not be complete.
     
  • As with most databases, there may be occasional quirks
    that crop up, such as a 2008 date appearing in the 2007 results.
     
  • We aim to fix problems as soon as we can, but if you spot
    anything odd, please get in touch.
