Yes, for the most part, O-3 thru O day is the functional fertile window. Very, very few of us can get pregnant from BD on O-4,5,6 or whatever and 99.9% of the people who think they got pregnant from BD on those days actually Oed the day that they believe they did.
BUT we don't know if BD on O-4/5/6 has any effect on gender swaying outcomes. Since we don't know why one attempt sways, we don't totally know if BD on O-5 for example could possibly affect things if you had another attempt on O-2 or whatever. We just don't know that. We don't THINK that it does since people are getting good results with every 4 days, but it is just not something we KNOW.
All I can say is that one attempt in O-3 thru O day is what I consider to be one attempt, and at the same time I would not want people to have attempts on O-4,5,6 while adding in one attempt O-3 thru O day because I do not think that's truly one attempt. Do I know this, no, but it is just my gut feeling.
