I tried a mixture of about 70/30 EGGSHELL/SATIN. It works. I can tell you that the paint has more of a sheen than satin, but is just below the hotspot level. I'm using a DLS8 projector ceiling mounted. I'm curious what would happen if I tinted the paint with a very light grey. Anyway, it's worth looking at. The paint really provides a boost over flat paint. Definetely better.
