Google PR predictor

[yandig]

I'm getting different results from a couple of Google PR prediction tools. From the tool here at Namepros (under Domain Services), my wine blog www.pinotgris.net has a future PR of 4 (currently zero). But, if I try a different tool somewhere else, it gives me a future PR=0. 8-X
Anybody know why these figures don't match up? I have 3 known inbound links that are from pages with PR 3, 4 and 5.
Thanks

Predicts a PR4 for my website, Black Toned. Hmmm, awkward as it's only been up barely a month. :P

When is the next google update anyway?

Iwebtools is pretty accurate guys.. The scrip they use has been in the past. Just have to wait and see. I reckon we are in for an update in the 3rd quater of this month.
