A note of caution from experience - I had my application for removal of restriction rejected by CAA for logging QXC as 3 flights.
This didn't cost me anything except time dealing with the CAA and having to get 2 more signatures.
Other instructors at my school logged QXC as 3 flights and got away with it.
Moral of the story is it depends who checks your application at Gatwick, so if you decide to chance it keep logging signatures in case it gets rejected.
