I understand this point, but the low drag of the rest of the car is present regardless of whether the wing is open or not.
The increase in speed that you get from opening the rear wing, should be solely the result of the drag reduction
of the wing itself (assuming it's not the trigger for stall elsewhere when it's open)
That's grossly inaccurate.
There is a field of flows around the entire car and the different streams interact in three dimensions. Think of a 3D lattice, or mesh. There is a "ripple effect" of changing the pressure in a given area on other areas.
Opening the DRS means more air static pressure behind not just the wing but pretty much the entire rear of the car.
Not sure if you missed this:
(assuming it's not the trigger for stall elsewhere when it's open)
Does not matter. Trigger or no trigger. Stall or no stall. Not having the blockage if the rear will will also reduce the drag of the surrounding areas behind it.
A good example is the McLaren "speed tail"
Talking about the RedBull DRS trick, James Allison interestingly said that the RB19 runs a lower ride height above a certain speed, that would cause problems if tried by another car...
It could be that the RB19 DRS has other effects than just reducing drag or stalling something.
