I don’t think it is possible to attribute any of the downed aircraft to any one pilot. Most of what happened can only be discovered from the pilots’ combat reports. For example Forbes is obviously describing the third Ju 88 that fell in the Channel near Lydd.

“I flew towards the diving fighters, but was unable to reach them before they engaged the rest of the squadron. Then I saw a He 111 leave the combat and start diving towards the coast. As no one followed him I dived on to him, and caught him up at about 10,000 ft. I closed and, after two short bursts, three or four of the crew baled out. As the enemy aircraft continued in an even dive I thought that the pilot might still be in his place. I therefore decided to destroy the e/a and set fire to the port engine. It crashed in flames either on the shore or just in the sea on the east coast of Kent.”
But other pilots may tell a very similar story. Zumbach gives an insight as to what was going on.

“I attacked a Heinkel 111 that popped out of the formation. with some others I started to pound him in turns. After a moment the gunner baled out. We were joined by three more machines which, hell knows why, decided it was their duty to shoot at this particular machine, while they had a whole lot of others above us. I got to it once more. After the burst it wheeled and rammed into a small town, knocking one house down and setting another one on fire.”
Lots of fighters firing at the same aircraft, especially the wounded ones.
