These are the settings I use. Indoors at my office you can see at the top I have 100-150 level range ambient lighting and that is from the past 2 days of watching at different times of the day and these have been bright and sunny days. I wanted that to be the lowest I could stand it to be which was the lowest minimum setting. From there I worked my way up the scale. Never saw any place I would experience anything over 10,000 that wouldn't be full sun so I made the big jump to full brightness there. Even on a bright day in a shady area, I could tolerate a 125 setting easily at the only place I could get the sensor to read in that 6k-10k range. I'm sure there'll be more tweaks. 15 levels in all right now.
