this is in reference to pplns. And i am thinking i misunderstood it. 

I know that payout is a constantly changing calculation based on the last several rounds, so I guess what i am looking for is graphical representation of the math that determines the pplns payout. This is so I would know how much work i have put into the last x number of rounds. Does this make sense?

Thats a good idea too. But, what i am asking is if there are 5 rounds, is there a way of knowing which round we are on?
