when "average" is selected for the temperature in the system tray, what period (length of time) is Realtemp using to make that average calcultion? Is it the past 10 seconds, 20 seconds, minute, 24 hours? I like having it show a relatively stable temperature instead of jumping around so much... but I hope it's still refreshing fairly often. The past 10 or 20 seconds would probably be good, I'm thinking.
