I know weight is related to PR and how many of your pages are indexed by google. So technically a BL update should get you more weight if you have more incoming links.
It's not all real-time. Poeple's caches might be filled with your old ones. The system updates at certain intervals. Whenever something changes/happens just sit back 24hrs, revalidate and then start worrying if it's still not all as expected.
I got more backlinks and i got a increase of 30k more pages although i dont see an increase in weight , am i doing something wrong.?
Someone want to explain how backlinks increasing would up the weight? Is that part of the calculation, google backlinks? As for pages... Well google has some messed up page counts on search. Are you showing 30k more pages via the API or just on search? I have one site that shows 148k pages (it has like 12k), and only shows 4 pages on the api.
