Collection information that changes every .5 seconds.

I am looking to use Sikuli to create an automation of some processes that I do manually now. In order to do this I need to collect data that changes very quickly then take the average of that data and store it to a parameter that is changed. I was wondering if this is something that Sikuli is capable of doing? Take two text lines every .5 seconds for 10 seconds and save that data to a spreadsheet under a certain parameter, then change that parameter and repeat the process x number of times? I know this is hard to understand and any help is appreciated.
