I know that the PR updates only like once every 3 or 4 months. With that being said I'm wondering if anyone has ran a test to see how many PR 0 links it takes to get a PR1... how many PR0 links it takes to get a PR2, etc. Obviously the amount of link juice it passes depends on the amount of links on page and several other factors, and I think that over time some of that link juice is still passed but I would think that someone at some point in time might have set up 400 domains and tested 100 of them and send each one 3 links more than the last so that the first link gets 3 links from each new domain, the 2nd gets 6 links, the 3rd gets 9, etc and the last gets all 300 remaining domains pointing to it. if the domain names are brand new, and create the same exact number of word post and everything else is the same, you should at least be able to come up with some sort of rough estimate for how many PR 0 links it takes to get to a PR1... For example you could conlude that if sites 0-62 are PR0 and 63+ are PR 1 or higher, then you need somewhere between 62*3=186 and 63*3=189 in his test. actually, first how many PR NA it takes to get to a PR 0, then to a pr 1, but whatever. has it been done? is there a rule of thumb or a rough estimate based on some sort of test or something?!

I was hoping you could isolate most of those variables. Say something like "with all other things being equal... it takes X PR0 to get PR 1" would think that by buying completely new domains and making them single post links on same wordpress plugin or something that you could still get an estimate even if it's like within 100 links it would still help.
