Can someone teach the UK Met Office how to calculate an average?

----- Can someone teach the UK Met Office how to calculate an average???
April Top Ten mean temperatures for longest reliable recorded series - Central England 1790-2007

From ranks 10 to 2, temperatures are in the 10.0° to 10.6° range.
Since today, the difference between the first and the second is no more 0.1°C but 19 times greater, as April 2007 records 12.5°C.
Now note that all time records with even higher differences to previous records were set in France, Holland, Germany and Switzerland.
Besides this, all these countries (except for a small area of Germany) as well as other areas in Europe (northen and central Italy, Croatian coast, most of Austria) had the hottest April on record.

Update: As of May 2, the Met Office issued no correction. Actually no other news were released on this subject after April 27....
