How many people that have taken high risks, or that have been infected with HIV can honestly say they know exactly when the infection date occured? It would be my guess that most people that take high risks do it more than once. I think that CDC gives a conservative window period for this reason. For example: If you had sex with someone who has the virus, began to have sex w/ them in april and continued to have sex until june,how would you know when your infection occured? To be safe you would have to assume it was at the last sexual experience. It seems it would be hard to assess the window period for most individuals, because most of the time infection date is unknown...

You're right, but when stats are collected, I don't believe they would assume that the last risky contact you had was when you got infected. In the situation you described, the CDC or any other organization would classify the person with an unknown date of infection. Most of the people who actually get infected with HIV generally live lifestyles that allow frequent risky behaviour. So when someone was found positive, if they assumed that the last exposure the person had was when they got infected, we would probably see stats that say the window period on average is something like 3 days. We know that's not true. I believe that organizations will only consider seroconversion time in an individual if they are testing for a particular encounter that they can date correctly.
But as far as testing goes, you have to consider the window period to start from your last risky encounter, for obvious reasons.
