Just can't see how anyone thinks they haven't got net lift there from that wing. It may generate vortices, which look uncontrolled vertically from the various representation appearing on here, that also makes the rear wing messy.
Those waterslides on the aston generate lift in isolation too. You can't look at an F1 part in isolation.
The Aston config doesn't (that's why the balance is superior across the chassis ) it generates low pressure yes, but that's largely enacted on vertical walls, well substantially it is, which won't lift anything. Brings lowered pressures to area infront of wheels and pulls in outlying stream to fill that volume to then go over the beam wing area. Draggy, yes, I'd agree with that, but flow not resolved until it exits over top of diffuser.
The difference of mid wing is that it's fully resolved as a wing in free air, and orientated to give lift (get any aerodynamicist to say otherwise) which has to be compensated by other wings (they alway have to run big wings) to get anywhere near the downforce overall they expect.
I can quite see the desire for "downwash" flowing over a sidepod, but this wing isn't that. It gives that direction but at significant penalty of lift which has to come out of the equation somehow.
That somehow is thorough loading other parts until it gives that force, but with very obvious drag. Just look at tgat speed difference when MV passed LH
They should try it with a great big gurney flap on trailing top rear edge of that mid wing to see if it shifts anything. That would give them something to measure.
