The interesting thing is how Downing fights over the channel, protect warships, and counter the LW, and it's counter multiple tasking. How much bomber command will risk daylight ops,
Hang on, it might be my poor comprehension at play here, but you seem to be saying that the RAF has to stop every prop supporting the invasion structure.
If so, it is, of course, complete nonsense. Dowding can choose which bit to knock out, or switch between them. It's just a detail whether the Germans are killed by RAF planes turning the landing sites into a charnel house, or drowning when the barges get sunk by RN ships with air cover, or being torn apart and/or drowning by RAF planes attacking the barges direct. Any of these lead to a bunch of dead Germans and an invasion in tatters. Dowding could use every single plane to escort RN ships to the barge fleet, and ignore everything else.
By contrast, the Germans have to protect against all threats at the same time. If any one of the props gets knocked away, they are screwed, so they have to protect each and every prop.
If RAF Bomber Command is escorted in strength by Fighter Command, you can be sure that Bomber Command will risk daylight operations.
It's the age old problem that the attacker - and in this case, the RAF is the attacker against one or more of the props of the invasion - gets to choose the time and place and nature of the attack. The defender has to respond with whatever they have in the vicinity.
