party bonus requirements and the wpc requirements the same?

cleared lot of hands playing party pot/no limit 25 on party since rake had to be at least 5 cents full ring or 10 not sure. Does empire/pokernow/multipoker all require pot to be raked minimuim 25 cents? Or are they like party where a 5 cent rake would count?? Also for empire, why does the bonus clearing rates look like partys while there is a table on the side were it says .50/1 limit requires 20x? i don't understand this. thx. the chart i m referring to his on bonuswhores.com empire poker page.
