How often Google updates its' webmaster. I've worked on HTML Improvements and would like to know when changes will be noticed.
I think every few days they update the info inside the WTD or maybe it's just a few days behind. Hard to say how long it will take to see results in SE's if any.
Google always keeps track all the data which running on the web. But, takes sometime to show you in webmaster tool.
Most data in webmaster tools is updated after Google crawls your site. The more active your site the more often Google will crawl it. As a new site, I would expect their to be a lag between your site changes and Google's next crawl.
I presume you have fetched the page as Googlebot and then click submit to index? This always works eventually but it relies and the Googlebot finding a significant change to the page. Things like the Google Sitelinks and the url removal work very quickly so the system is very responsive
