let's just look at @digitalmind:
Week 3, @digitalmind nominated you, @elsiekjay and when you, @elsiekjay submitted an entry, @digitalmind checked one level with *.
Week 4, you, @elsiekjay, nominated @sherbanu, and @sherbanu submited an entry - and you, @elsiekjay, have earned a first level * and @digitalmind earned two * in a rwo - one * at each level - week 3 and week 4.
So, now it is week 5 - level 3 for @digitalmind in this reward but level 2 for you, @elsiekjay, and for @sherbanu, it is level 1 in this "game" or "contest" and IF @sherbanu nominated someone and s/he submited a valid entry to this week's Pay It Forward contest, @digitalmind wins "3 level down in a row" or three consecutive weeks for a nominee who then submitted a valid entry to Pay It Forward.

The simple answer is - you tell me if you have earned any * and let me verify it and post it on the list. And, right now, two are one * away from winning and there are 4 rewards total, so far.
