what is the real window period

hi experts here in this forum. I do understand the guidelines and stance this forum follows is the guidlines of the fda and cdc makes. Can someone from the experts here show me some link of cdc guidelines from the official website of cdc of fda saying that the window period is 3 months. i had given this link:

  In an adult, a positive HIV antibody test result means that the person is infected, a person with a negative or inconclusive result may be in the “window for 4 to 6 weeks but occasionally up to 3 months after HIV exposure. Persons at high risk who initially test negative should be retested 3 months after exposure to confirm results

But when i search it in the official website of the cdc it is not there. So how the experts here tells they follow  cdc guidelines which the link they give is not on the website of cdc. and also can some experts here gave some links or guide lines saying that those 3% of the people belongs to the People on chemo, people on antirejection drugs for transplants, IV drug abusers and people with a severe immune depressed disease. Because this is the direct quote from cdc website.

How long after a possible exposure should I wait to get tested for HIV?
Most HIV tests are antibody tests that measure the antibodies your body makes against HIV. It can take some time for the immune system to produce enough antibodies for the antibody test to detect, and this time period can vary from person to person. This time period is commonly referred to as the “window period.” Most people will develop detectable antibodies within 2 to 8 weeks (the average is 25 days). Even so, there is a chance that some individuals will take longer to develop detectable antibodies. Therefore, if the initial negative HIV test was conducted within the first 3 months after possible exposure, repeat testing should be considered >3 months after the exposure occurred to account for the possibility of a false-negative result. Ninety-seven percent of persons will develop antibodies in the first 3 months following the time of their infection. In very rare cases, it can take up to 6 months to develop antibodies to HIV.
So where do experts here gets the information for those 3% people may take up to 6 months are those completly ill
