I agree with you that quality is important, but is that true to get PR2 online need 1 PR2, so If i want to get PR4 I only need 1 PR5?
Well, i own domain name called birja.jobs and you know what? google gave me PR3 in 2 weeks, i didn't work on this project yet, will launch in august and will gain backlinks at the end of the year. Nothing with backlinks i think.
If you have great on page seo you do not need as many backlinks. IE good seo on page need 10 backlinks--bad on-page seo need 100 links. Variety is best--only 20-30% on home page--most should go deep. best wireless MLM free Moto Q see WirelessKeith.com -- sign 3 and your service is free.
I do not agree with you .Google has their own algorithm for this.Only backlinks are not necessary to increase page rank.There are many other stuff,you need todo to increase page rank.

I also agree with that, if you have backlink from higher PR site your PR will be high soon... 1 PR8 is much better than 100 PR0 links...
PR depends on the content quality, backlink quality and number of back links... the list is as per the priority order so the content quality is most important factor to earn PR
