Yes, but don't forget that the national average includes ex-miltary and also experienced pilots with established foreign licences who simply need a conversion and those who are experienced, but have let their licences lapse.
There is a heck of a difference between an ex-Tornado pilot with 2000 hours doing a civil rating at anither college and an ab initio with 150 hours on Warriors and Senecas doing it at Oxford.
Oxford only deal with ab initios. You're not comparing like with like.
