Easy to prove..
HTC,
Go into EGHQ anytime between 0800 and 1200 and it is full of people who have been waiting or will be waiting for hours. Last time I was there at 0830 after returning from an India flight I was told 4 hours and there were 120 names on the sign in clip board. Now pilots can only go to SZR so that's a plus. Max duty then go home change then drive myself to SZR to wait again. Yea...... Also, I personally had a 5 month period last year without a single layover so 9 turns in a row sounds very realistic as that doesn't even cover 1 month.
