I thought I knew what this value does, but now I'm confused again.
When using the Epson 4870 this number gets set after doing a preview.
Depending on the film being scanned it is usually around 2.2 for me.
I've tried changing this manually to see if I could get the low values
to move away from 0, but it doesn't seem to have much effect until
I go up to 12 or so.
Does this value do anything, or is it only meaningful on some
models of scanners?

It's functionality depends on the scanner. Some scanners don't allow
to change it (I think the option is hidden then), some only change in
certain steps, and others allow fine exposure time control (as
witnessed by a change in scan time).

Depending on the version of VueScan you use, you may also want to
check against another version, to see if anything changed in VS.
