Testing the rake at .25 -.50 limit on FTP

[formula72]

I am putting aside $200 dollars to test out the lowest limit to see if i can beat a 5% rake with poor players and if so how much. I plan on 4-6 tableing 9 handed games and play until I reach 50,000 hands. I know it sounds fullish but is is a cheaper way to find out. I plan on it taking me about two months. Has anybody ever tried this? Any sugggestions?
