I think there were discussions on this in the past - but I can't find a definitive answer. When racket specs are published, and they say 'racket head: 98 sq' - how exact is that number? I'm asking since I was doing some measurements on my own (I know, I have too much time) and the area I was getting was consistently bigger than what the advertised number was. Like advertised 95 was more of 99 sq, 98 was around 105 and so on. (tried with few head rackets). any thoughts?
