because it is measuring the sg of the liquid, so the denser the liquid, the higher its sg, the more "crap" there is in the water to hold the bulb up. the less stuff in the liquid the lower the sg the further the bulb falls. as you read the number from where the stem cuts the surface you have lower numbers at the top as more will be under the surface in lower sg liquids

I think it just to confuse people as it could just as easy been designed the other way, another example is wire gauge size the higher the gauge number the smaller the wire diameter. If you think about it the usa system is just about opposite of the rest of the world and for no good reason.

The scaling is not linear.
It follows a phsical law or two, and I'm a bit rusty on this, but if it is working to a logarithmic scaling, then indicator marks are going to reduce as the scale goes down.
