Wings can create negative lift, i.e. suck the car to the road. Spoilers can negate lift by not allowing air to accelerate over a surface and create downforce. Negative lift is far better than downforce as downforce is created by increasing aerodynamic drag. Lift (positive or negative) is created by accelerating air over a surface, i.e. Bernouli's law.
The term "positive down force" should be used, and not only for cars.

So what's up with this? The 99 owners manual states up at 75 MPH, down at 37 MPH -- no conditional info for a cabriolet.

Is the lift mechanism hydraulic like the Turbo? Or is electric? I've been through the full process servicing my Turbo, which is notorious for hydraulic failure. Curious if I should look for a similar issue with my C2?

So, if you raise the spoiler with the button, it should stay up for the drive.

When I raise the spoiler using the button in the footwell it will remain up until I turn off the car (and remain up until the next drive). When I am driving on a track, I typically raise the spoiler with the button before I grid the car. I'm not sure if there are any tracks where my speed drops below the low-speed threshold, but I figure I don't need the spoiler going up/down during a track session. When I return to my spot in the paddock, the spoiler will still be up. If I turn the car back on, and just start driving, it will stay up until the first time my speed drops back below the threshold, then it goes down. For my next session at the track, after I fire up the car, I cycle the spoiler back down and then up again, using the footwell button.
So, if you raise the spoiler with the button, it should stay up for the drive.

But here we are. I would think keeping it up on the track would be of benefit since it's running cooler air when up?
