I'm back in the office today (Saturdays of all days!!!) this is after a well deserved week off though! I'll get on it and get it reviewed for you!
I am at 83% now and I count 6 thus far, one can only assume 2 more reviews too. I heard that part of the 'algorithm' that goes into the % is the reviewers 'points' earned on the forums but it's a guess all round I think.
Edit: Btw after checking your game page I see it's at 50%, mine shot up to 50% within the first two reviews. It slowed down after that.
Check back soon bud!
