Actually, much to my surprise is was a lot faster than even three months. It happened only about two weeks after the site was soft launched. I had said so in the following post:

I think it is impossible to know what mattered most in terms of the rapid page rank adjustment, but some of the factors I think are most important are the following:
1.
A lot of the content on the site was previously on other authority sites of ours, and we did 301 redirects from the former location of the pages on those sites to the corresponding new pages on the GamingMeets.com website.
2. The cross-linking infrastructure we use on our sites means the moment the site went live the thousands of links from other sites to the moved content became links to the new site. And since those sites are well respected by Google, it means Google was rapidly aware of all the inbound links to the site.
3. The site itself is quite deep with several thousand pages of really good, related, cross-linked content.
4. We had done a good job of QA testing related to how the site looked to search engines like Google using the screaming frog spider. The result was we verified we had good titles, descriptions, etc. for every page on the site from the beginning.
5. From Google webmaster tooks we know that all of the pages on the site were spidered within just a few days of launch.
6. Finally, I think that we just got lucky and that Google updated page rank just after it happened to have seen all of our pages, so the typical delays on that front were avoided by pure chance.
