You've done well, I've spent £8k already (52hrs) and still got QXC and GST to go. And I didn't buy a Bose headset either!
Ouch
Word of advice regarding the QXC... Don't plan to do it when there is a major air display on nearby. My two stops from Thruxton were Wellsbourne and Blackbushe... Unfortunately Brize and the surrounding area was completely off limits due to Fairford... Certainly tested my nav skills that day!
