These are the settings I have finally settled on:
CPU max 729.6
interval 2000ms
steps 1
load max 30
load min 15
jump max 50
jump min 3
Idles at 364.8.
I changed from 2 steps to 1 step because I was getting a SOD every day or 2. I think the 2-steps made it idle too low.
I've been SOD-free for 5 days since changing steps. I have also been able to increase my CPU max from 691.2 to 729.6.
As an added bonus, I'm getting great battery life! (Used phone all weekend on a single charge!)
