But what about my assumption that the lift side of the rotor is generally

this depend on the particular ridge and the particular day?

I'll be surprised (shocked?) if anyone can point to a rotor that ever lies
UPwind of the wave-generating geographic feature, if that's what you're
wondering about,...

No. I'm only talking about rotor that is formed downwind of the wave-generating topographic feature (aka Ridge A).

My thinking is that for a wind blowing towards the east, the top of the rotor is also blowing east and the bottom of the rotor is blowing west, so the lift side of the rotor is to the west of the sink side. This is idealized because if the feature causing the wave is convoluted and irregular, all sorts of chaotic interactions can result in unpredictable patterns.
