Bing api difference with bing.com

I have did many tests with this api data,some are exactly same like the bing.com when the indexed numbers is lower. Check with a site which have a big bing indexed numbers,after you go to page 5,you will see the indexed number changed and have big difference with the top 4 pages,this one its not like the google,google keep indexed numbers not changed for all the pages.So i think the number from bing api is the exactly bing indexed pages,the bing.com results is a valuation when it’s a big number.Also the api number is close to the bing.com reulst,at least it’s closer than the number which got by crawl the page .
