Well, most of us know about the Predicted Pagerank or Future Pagerank technology 
which helps any webmaster guess his/her site's Pagerank on next Google Pagerank update. According to an estimate Google updates its Pagerank Datacenters every 3 months on average.
This technology actually makes use of the backlink technology and accordingly predicts the pagerank using the Google Pagerank Algorithm. The more the backlinks from Search Engines and High Pagerank websites the Higher will be your Pagerank on next update. However, more backlinks from a lot of Zero Pagerank websites can be bad for you too.
iWebTool Pagerank Prediction is a likewise very beneficial tool to help you calculate your site backlinks and predict your pagerank. The tool is not 100% accurate however it is accurate in predicting your site's future pagerank to some extent.

Its been a fortnight since i have been running Sizlopedia and i have been working almost 24/7 for its Search Engine Optimization. So, today when i checked my predicted Pagerank with iWebTool, it has come out to be 4. Take a look:
Sizlopedia is a technology blog created by Saad Hamid, a problogger from Pakistan.
There was a serious disruption in PageRank recently, wasn’t there (with lots of pages having their rank downgraded)?
I wonder what page rank prediction tool could predict that
Actually that downgrade or fall of Pagerank only happened to sites which were involved in Paid link activities.
It has no relation to the real Pagerank algorithm so I guess pagerank prediction tools cannot predict such behaviors.
What is happening to Pagerank Prediction tools? All of them are showing Zero Pagerank.
