If the QNH on the day meant he was close to the same altitude as you then I understand. Hence the question.
I can't remember the actual QNH, but I figured that FL35 was about 100ft below me so I climbed to give at least 500ft vertical. I actually think on looking back I must have been at an altitude of 3,500 not 3,000.
