Love the challenge, and don't mind egg on my face if I am wrong.

For reference, but no antenna on the car, no washer nozzle, and no wiper:




Baseline: Very good flow, isn't it? I'd be pretty happy with that.

Altered 1: I'd be reasonably confident you've added a fence/lip (eg a 1-inch high vertical plate or similar) that causes separation from the top of the hatch.

Altered 2: A harder one. My wife (who has watched aero testing tufts for about 25 years) says the wiper has been put back on. I say the antenna has been put back on.
