If there is a value somewhere in the static addresses that I know gets read once every 3 minutes, is there a method I can use to track down that value as time goes by? So after 9 minutes I would find all values that were read 3 times, and so on... continuing to weed down over time based on the increase of reads?

My first thought was Ultimap but it doesn't seem like the instruction is only running once, so that didn't narrow anything down.

Any possible way to know how many times static values in the main game exe have been read, but without knowing the address of the value? I need to identify any that get read once every 3 minutes, and the value will never get changed, but I also DO NOT know the value either. All I know is it's read every 3 minutes.
