I have tried it with and without the aether dimming curves. Without the dimming curves it is very pronounced at 158 to 161, but you must leave it at that setting for at least 30 seconds. After 30 seconds, you can go up and down, and every time it hits the 158 area it flickers very noticeably. As I said, I was demoing the aether to the Exotic Computer Society of San Antonio (they are also hardware hackers) and they noticed the flicker without me even mentioning it when I accidentally ended up at 160 on red.
I know you are very busy with 3 COOPs running and you have other fish to fry, but when you get a chance, please check it out.
Thanks,
Charles
