I recently noticed another complication for this analysis.
I’ve got a single hose AC that’s closer to the window than yours, with some gaps near the hose that let some air in from the outside. That means I’ve accidentally set it up to partly act as if it had two hoses. At one point the AC reported its intake temperature at 86F, while a distant part of the room was 80F, versus around 95F outside. [The AC is nowhere near as effective as these number suggest. Mostly the room has enough insulation to delay the effects of the outside temperature by hours.]
Yup, I think that’s plausibly an issue for my setup too, although I didn’t park the AC too close to the window. At least we know what direction that problem should push: it should make the one-hose more effective in my test than it would be for someone with a better-sealed window.
You’ve convinced me of your main points.
