We ran a test match and ELFv2 lost 34 - 62 against LZ-204 at 1600 visits
each, so that's about +100 Elo in favor of LZ at visits rather than time
parity.

This would mean going 800p -> 400p gives -200 Elo? Seems more than I
would expect.

I think I'd want to do more testing before forming an opinion :-)

Smaller networks have more overhead (heads etc are fixed), so it's
closer to ~60%. Probably depends on the GPU too.
