It is not easy. Each setup is different. Someone could write a program to run for a few hours to work it out. I have had good results running at 30/35 and max. I get a much lower noise floor at the 30/35 settings. I am still experimenting. One change at a time. Having collectd graphs from Joe’s scripts makes things a little easier. I am able to look back hours, days, weeks. I just need to note when I changed the settings.
