BTC per day rates for pools?

[TheSmo]

Hi all,

the clevermining-pool claims, that you get 0,01xxx BTC per day per MHash. I don't know, if this number is correct ot not. However: I am missing a transparency like this on other pools.

So my question is not "what is the best pool", but:

Is there a way to find out, except for mining on the pool for [ x ] days and compare it then? Are there more pools with high transparency (e.g. hashbros is very transparent )?
