I see 3 days, past week, 1 day, and next week in your post.  Are you sure you understand how BTC mining actually works?  The math will never work to the timetable you are working with.

All pools are expected to hit 100% statistically over time and the real separation comes in 1) does the pool give transaction fees to the miners and 2) what are the pool fees.  Once you understand this concept, short term physical comparisons become an exercise in futility...they simply can not resolve anything at all.  Making business decisions like that can become disastrous.  You may as well flip a coin...it would probably give you better results.
