Really?Sorry to hear that..Some of my sites are predicted to be PR4,I've no idea that if they will get PR4..I feel a little upset now
before it predicted my site 3 and i got ! now its predicting pr4 in future for my site and percentage is above 70. Lets see what happens.
I think PR prediction tools are like horoscope softwares. If they are correct in prediction, say they are great. If they are incorrect, say you are unlucky. nb.
Take them with a pinch of salt - i run around 60+ websites my main 5 have been checked with the iwebtool PR checker - Our main site had prediction of PR6 - nope got pr4 other 4 predicted pr5 nope pr4 - in all just keep looking at the live ranker on http://livepr.raketforskning.com/ - this will give you a real idea of what the datacenters are doing!!
