I have the "+Add Profile" screen set very close to your settings. My Screen Off priority is 98, the rest are identical to yours. With my fingers I could never get it to stay at 99. Does that make much of a difference?
Second question: Since I have overclocked my nc to 1100 mhz, on the main screen I have the max set to 1100000, that is 1100 max. Does the overclock have much effect on battery life? Should I throttle it down here when I am only using the nc as a reader or in other low power situations where battery life is more important than power?

The 98/99 priority doesn't make a difference as long as it is higher priority than the other profiles (the slider is not easy to get just right). I am playing with some other SetCPU settings (and will post later) which will automatically scale you up or down depending on activity requirements.

His thread was written for the rooted B&N version, so those settings are perfect...they are actually good for any ROM as their functions are simply how the CPU handles speed.

Here is an alternative to Rico's settings I have been playing with. I haven't noticed any obvious difference in battery life from Rico's settings. The advantage is that instead of the processor jumping between Max and Min, it ramps up and down to the frequency needed so it might only run at 600MHz for simple tasks and Max MHz for things like HD video.
Feel free to try it out and leave feed back if you notice any pros/cons.
Main Tab:
Max slider should be all the way to the right for your max clock speed (800, 1000 or 1100 MHz depending on how you have setup your Nook)
Min slider should be all the way to the left (300MHz)
Scaling should be "conservative" (ondemand - jumps directly to max and min settings as needed; conservative - ramps the settings up and down between max and min in steps as needed)
Profiles Tab:
Enable should be checked. Notifications *preference*.
Create Profiles-
Screen Off - Max 300MHz, Min 300MHz; Scaling "conservative"; Priority 98
Charging/Full - Max *highest available*MHz , Min 300MHz; Scaling "conservative"; Priority 95
Battery<35% - Battery 35%; Max 600MHz, Min 300MHz; Scaling "conservative"; Priority 90
Battery<50% - Battery 50%; Max 800MHz, Min 300MHz; Scaling "conservative"; Priority 85
Advanced Tab:
Sampling Rate - 300000
Up Thershold - 80 (bumps to the next higher frequency when CPU use exceeds 80% on current frequency)
Down Threshold - 33 (bumps to the next lower frequency when CPU use drops below 33% on current frequency)
Ignore Nice Load - 0
Freq Step - 5

That my, friend explains a lot of things for me. Watchdog has been piping up about SetCPU all day I have been getting warnings, 70,80,90% above threshold. Just switched off my profiles and zing. My home screen scrolling and animations are still a little choppy but this help thanks.

Very useful info.
So, do U suggest for people who are interested fof large power autonomy, to forget CM7 roms??

As rico said, the very early development build that is currently available for CM7 has some issues with setCPU. That being said, under the stock clock speeds the battery life isn't much different than it was on Froyo or Eclair. However, with overclocking it seems to eat faster. The same goes for phiremodv3 since it's built on the CM7 code. So for right now, don't leave your charger at home depending on your usage needs. I will let everyone know when setCPU (or alternative) works with the CM7 builds.

SetCPU is awesome! It extends my battery life by hours. Definitely worth the $2.

The lower you set the cpu clock while charging > the less power your device will use > the faster your device will charge while charging.
...which is want most of us want.
But I see your logic, that is how all laptops function. Ultimately it's to the user.
