When Google crawls and indexes a new page does it show up immediately in Google search - "site;"?

We made changes to a site, including the addition of a new page and corresponding link/text changes to existing pages.  The changes are not yet showing up in the Google index (“site:”/cache), but, approximately 24 hours after making the changes, The SERP's for this site jumped up.

We obtained a new back link about a couple of weeks ago, but it is not yet showing up in OSE, Webmaster Tools, or other tools.

Just wondering if you think the Google SERP changes run ahead of what they actually show us in site: or cache updates.  Has Google made a significant SERP “adjustment” recently?

Thanks.

"Google SERP changes run ahead of what they actually show us in site: or cache updates"

Precisely.  Those tools are not real-time by any means, and are to be used as a guide, at best.

That's what I suspected -- thank you!
