Comment on Can someone explain to me how a ventilation fan can suck LESS when on high compared to low?

The probably if you probably don’t have the intake part of the equation. A lot of more newer, more powerful hoods require an air exchanger, that blows in outside air to equalize the pressure from the hood blowing air out.
The faster the hood blows, the more it struggles to pull air as the pressure in the room drops. An exchanger fixes that.

At worst though, it should be pulling in as little air as when on low, not less.

I think it initially does, but then the difference in pressure basically works against it, as the pressure inside drops
