I hope it holds for you to brother. Unfortunately I had a fake 'stoked' period like this a few months back, a new site went to a PR6 for a few days then down to a PR2 within 72 hours. No tricks were involved either, was just a brand new domain, did a lil work on it, nothing fancy and bamm, a HIGH and a fast LOW.
But hopefully YOURS sticks, mine I'm still working up the ladder.
