My understanding is that, post SDSR and Harrier draw down, 60% of CAS tasking (training of course) is going un-supported. Draw from that what you will.
This is just the tip of the iceberg. I fear we will see this type of occurrence going on a lot more. Of course our dark green colleagues will simply blame us for not turning up, conveniently forgetting of course that we have been forced to cut way too much of their 'enabling assets'.
