I don't know the issue you two have with each other and I'll ignore that but:
From what I was reading yesterday, it is often more profitable with say 2 as opposed to 3 adsense blocks. The reasons for this is that it will often run out of ads to display if you use 3 on a page. As well as this, your most profitable ad may be in the middle of the page which may mean that 2 other ads will have already taken the most profitable ads.
Also, having a zillion ads means that your bounce rate will go up as people will leave your site far quicker.
These are my opinions combined with a small amount of research. I think I'm right but happy to be proven wrong
I would agree Sparky - it may in fact be that some pages have 1, some 2 and some 3 - it doesn't have to be a set number right throughout a site of 300 plus pages, mix it up a bit. As long as the suggested maximum per page is not exceeded through lack of knowledge of that number.
My query has well and truly been answered - 3 is the max - thanks gents. Oh, and it's OK, I will pick up the rattles thrown from the prams.
I don't think I will ask the next logical questions of placement, size and colour as I do not wish to be responsible for WW3
