To keep the pot boiling, I've put together a list of Mannock's claims I believe to have been deemed "decisive". Where possible I've quoted from the relevant RFC or RAF Communiqué and/or the 2 Brigade List of EA shot down and driven down out of control (Air 1/1580/204/81/52).
As ever, constructive comments, nit-picking etc are welcome:

RFC Communiqué 87: An attack on German balloons was carried out by seven Nieuports of 40 Squadron. The pilots crossed the lines at about 20 feet and, as on a previous occasion, artillery put a barrage on the German trenches, while 12 other aeroplanes crossed the lines at the same time at a considerable height in order to draw the attention of anti-aircraft gunners. Seven German balloons were destroyed; three caught fire high up, two burst into flames when near the ground, and two when on the ground. The names of the pilots who took part in the attack are: 2nd Lts L L Morgan, C S Hall, C W Cudemore, H B Redler, E Mannock, J Parry and Captain W Nixon who failed to return.
