$25 PL/NL rake value

Is there any value in 4 tabling $25PL/NL games for rakeback? I am currently playing for my party bonus (2900 regular points for $215) which is roughly 15,000 raked hands and noticed I can get about 1000 raked hands (200 pts) in roughly 5 hours if I 4 table. I do have a rakeback agreement on Empire and have only played Omaha 8er up to this point for rake, but at times it's agonizingly slow. My rakeback accumulation has been pretty meager.

Any feedback would be appreciated [img]/images/graemlins/smile.gif[/img]
