He is getting on now and his mind isn't what it used to be!
True! How true!
Finger trouble on the old electronic calculator. However my trusty old manually operated Blundell Omega says 94% but only on the data provided.

The website data is another matter. There is No Computed Data for 17 events - I guess thats the "give or take"? Of these it is apparent that several "appearances" consisted of fly-pasts from a single departure. We seem to have have 3 events on 25 July, 2 on 23 August, 2 on 5 Sept, 4 on 11 Sept, 3 on 13 Sept, 2 on 20 Sept and 4 on 27 Sept. Thats just seven departures for a total of 20 appearances. The total number of scheduled departures not cancelled for weather then becomes 48 with 5 technical cancellations .

For the 48 possible flights, of which five were cancelled for technical reasons, the depatch reliability is then 89.6% which is amazingly good. Bloody good show!
