After 3 years of ChE school - where I was first exposed to the charts - I decided I didn't want to be a "plumber", so switched to Ceramic Engineering & Materials Science, where I was exposed to it again, this time as part of controlled drying of clay bodies. I later learned Ceramic Engineering is simply high-temperature chemical engineering anyway, and after 4 years of product/process development work for Corning, I worked in the chemical industry for 28.

I have the 700, but I don't think going to a larger motor for more atomizing power is the entire solution. I believe the larger units are intended for longer throw, so the selection should be based upon the size of the GH.

When the water is atomized, I think they all pretty much average about 40 µ droplet particle size. At low flow rates, they are ejected from the fan and disperse, mostly evaporating. As you increase the water flow rate, the density of the fog increases, so there is a greater probability that the droplets will coalesce and drip, rather than fog.

The Jaybird info even eludes to that, as for one of the XE models (I don't recall which one), they have a low-flow controller for "dry fog" applications, and larger ones for misting.

I suppose the real solution would be larger diameter to reduce the fog density, but that would be an entirely different device.

If you do get an Aquafogger, remove the safety grill from the front (they tell you to do so only if it's elevated and out-of-reach), as it accumulates a lot of the fog and drips heavily if you don't.
