Rear flap opening range with the sun roof open.

I hadn't noticed this before on my 991 GTS, when driving normally, I can not see the rear flap open in my rear window mirror. However, when I open the sun roof fully or tilt, the rear flap angle increases and is visible in the rear window. I expect it is something to do with the aerodynamics with the roof open.

I have had several conversations with my OPC as my rear spoiler does not come up at all when exceeding 75 mph in normal mode (in Germany and on track) Visual and photographs prove this. The OPC insists that the first up position is a very small lift. On the track with Sport Plus selected it raises correctly to position 3.
By accident I found out that this happens in normal mode at over 75mph (French motorway) when my passenger opened the sun roof accidentally. The noise was horrendous so we shut it immediately and the spoiler retracted completely.

Personally I cannot see why anyone would want the sun roof open at those speeds, most uncomfortable and noisy, micky mouse up and over design totally different from the fully slide away one on my previous 997 Turbo.

I asked when the spoiler would com up completely in normal mode (sunroof closed) but received no reply.
