I added a page at midnight
At 2.00 am it was already indexed and I found it searching Google. But there was a spelling mistake in the title so I fixed it.
At 3.30 the corrected page was already indexed and visible
The site is only a PR3 but the googlebot seems to like it so I know now where any new site will be promoted.
To get into the system quickly you need a site that gets indexed often. If it's one of your own so much the better.
