Internet speed test software

Hi. Im new to these forums but not new to Windows 7. :) Im a little obsessed with my internet connection speed at the moment and im running speed checks every hour or 2 and comparing the data to get a beter idea of busy hrs etc. What im looking for is a software to do this for me, i.e. do hourly speed tests and compile the data onto a spreadsheet, completley independent of user input. So basically I can get on with whatever im doing and this software will do the biz for me. Ive searched and cant find anything to suit my needs, but on the off chance that someone here knows of such a software I though id try my luck. Failing this I suppose i'll have to have a go at writing the program myself. lol. thanks for any input.

Thanks for the reply. Much obliged :)
